The earliest mark of Norblin which refers to fusion-based silver deposition. It has the inscription in Polish "WARSZAWA NORBLIN & Co" ("WARSAW NORBLIN & Co") + the year of production inside the oval. Very rare.





 

Next Norblin mark which also refers to fusion-based silver deposition. It has the inscription in Polish "WARSZAWA NORBLIN & Co" ("WARSAW NORBLIN & Co") inside the oval + one French word "PLAQUÉ" under the oval. Very rare.








 

This Norblin mark is a variation of the mark No.2 with the writing of "NORBLIN & Co" in two lines instead of one. In contrast to the previous mark in some cases it has a dot (!) after the word "PLAQUÉ". I think that the presence of a dot could be connected with the use of galvanic-based silver deposition, while the absence of the dot could be connected with the use of fusion-based silver deposition. Very rare.

















 

Next mark differs from mark No.3 by a rounder shape of the oval. Again, the absence/presence of the dot after the word "PLAQUÉ" could be connected with fusion-based/galvanic technique of silver deposition. Very rare.



















 

According to the description of Wysiadecki collection [6], items 166-169, this Norblin mark differs from the mark No.4 by the disposition of French inscription "PLAQUÉ", which is laid in a cartouche (rectangle) below the oval. In addition, in some cases the rhombus with "N" letter is used. The presence of "PLAQUÉ" inscription in a cartouche means fusion-based silver deposition, while the additional rhombus with "N" letter refers to galvanic technique of silver deposition. Such system of marking is similar to that used by Fraget in the same period. Very rare/Extremely rare.

Next Norblin mark refers to only fusion-based silver deposition. It consists of the inscription in Polish "NORBLIN & Co PLATER WARSZAWA" ("NORBLIN & Co PLATE WARSAW") inside the oval, the size of which is about 7.8 mm x 9.4 mm. Note the famous French sign "Fleur de Lis" (lily flower), put to the left and to the right of the inscription "PLATER", which is probably connected with the French origin of Norblin company. Very rare.






 

This Norblin mark refers to galvanic silver deposition only. It differs from the previous mark No.6 by two characteristic details: the absence of the oval and the presence of the inscription "GALW". Note  the colon (!) after the inscription "GALW" made of    two quadratic points, which again corresponds to Fraget mark    used in the same period. The inscription "GALW" is the shortening of Polish word "GALWANIZACJA"     ("GALVANIZATION") and refers to the method of silver deposition. The Polish inscription "NORBLIN & Co GALW: WARSZAWA"  ("NORBLIN & Co GALV: WARSAW") forms the oval. The size of the oval is about 7 mm x 9 mm. Similar to the mark No.6, the stylized French symbol sign "Fleur de Lis" (lily flower) is used. In earlier version of this mark the catalogue number with a large dot (!) was applied. Later, similar to Fraget mark of the same period, the small oval with "N" letter appears, which means “normal thickness of silver deposited onto the surface of the base metal (usually on brass)". Note the simultaneous disappearance of the dot after the catalogue number. Finally, in the later version of this mark, the circle with the swan image under the Star of David in some cases was applied. Very rare/Rare.
























































 

Next Norblin mark is the last one which refers to fusion-based silver deposition. It is mentioned in the description of Wysiadecki collection [6], items 196 and 207. It is similar to the Norblin mark No.6, over-printed image with the Coat of Arms of Russian Empire (two-headed eagle, version with a "separated" crown, used in 1857 - 1883). As I do not possess the photo of this mark, I am presenting its characteristic details only. Extremely rare.


















 

This Norblin mark refers to galvanic silver deposition. It differs from the mark No.7 by two characteristic details: firstly, the reappearance of the oval, and, secondly, the presence of the Coat of Arms of Russian Empire (two-headed eagle, version with a “separated” crown, used in 1857 - 1883). Note that the colon after the inscription "GALW" is made of two quadratic points as before. Attention! Very often one of two points is missing. The size of the oval varies between 8.1 mm x 10.7 mm and 8.5 mm x 12 mm. The circle with the swan image under the Star of David is absent. Sometimes, the letter "N" in a small oval, which means "normal thickness of silver deposited onto the surface of the base metal (usually on brass)," is present. Common.











































 

Next Norblin mark refers to galvanic silver deposition. It differs from the previous mark No.9 by three characteristic features: firstly, by disappearance of Russian State Coat of Arms; secondly, by appearance of a dot (!) after the word "WARSZAWA"; and, thirdly, by the use of two round dots to form a colon after the inscription "GALW". The mean size of oval is 8 mm x 10 mm. Sometimes, the letter "N" inside a rhombus (or inside a small oval), is used. That means "normal thickness of silver deposited onto the surface of the base metal (usually on brass)". In some cases, the circle with the swan image under the Star of David appears. Common.















































 

This Norblin mark refers to galvanic silver deposition. It differs from the mark No.10 by four essential features: firstly, the appearance of Russian State Coat of Arms, which according to last editing made in 1883, has a crown "glued" to the two-headed eagle; secondly, the use of Polish inscription "NORBLIN i Ska" instead of English "NORBLIN & Co"; thirdly, the appearance of a dot after the word "GALW" instead of a colon, and fourthly, the disappearance of a dot after the word "WARSZAWA". The mean size of the oval decreases down to 4.9 mm x 6.7 mm. The letter "N" inside a rhombus means "normal thickness of silver deposited onto the surface of the base metal (usually on brass)". Rare.














































 

Next Norblin mark also refers to galvanic technique of silver deposition. It differs from the previous mark No.11 by a return from Polish inscription "NORBLIN i Ska" to the English one "NORBLIN & Co". The mean size of the oval corresponds to that for the mark No.10, namely, 4.9 mm x 6.8 mm. The letter "N" in a small oval means "normal thickness of silver deposited onto the surface of the base metal (usually on brass)". Rare.





















































 

This Norblin mark also refers to the galvanic silver deposition. It differs from the previous mark No.12 by the printing of two main mark elements, the oval and the two-headed eagle, as bas-reliefs on a flat surface. The size of the oval varies between 4.4 mm x 5.8 mm and 5.3 mm x 7.1 mm. The letter "N" inside a rhombus (or inside a small oval) means "normal thickness of silver deposited onto the surface of the base metal (usually on brass)". Relatively common.

































 

This mark of N.B.W. company was applied when using the newly-invented tin alloy VERIT as a base metal for silvering. This mark consists of convex triangle of 6.9 mm height and 7.5 mm width. Inside the triangle under the Russian State Coat of Arms is the inscription "VERIT N.B.W.". Rare.


















 

A variation of Norblin mark No.13 without the Russian State Coat of Arms. Rare.
