Unknown marks

[paulb4]

Thank you for any help. Am not sure if I'm in the right forum. The starting with a "c" throws me off and the only "EP" I find is Elias Pellatreau (I or II) but the letters don't quite match up and are inside a shield with what seems to be a crown above them. My notes say the pattern is Hanoverian.

Hello.

Your picture of the marks is upside down.
EP stands for ElectroPlated.

John Harrison, Norfolk Works, Sheffield, England.
Your mark was used 1843-1865.
Firm became "& Co." in 1866, Ltd. in 1873.
Taken over by Richard Richardson in 1891.

He was the first to start electroplating in Sheffield England.

Pat.

Thank you. Am curious what the backwards "C" is for. I appreciate the help very much. Such a great forum!

American and English Plated producer had a letter code for their »Plated« quality

Hello »paulb4«

The continental European »Plated« producer had as quality sign the indication of gram; please read this: http://www.925-1000.com/a_platenumbers.html

The American and English Plated producer had a letter code for their »Plated« quality; e.g. »A1« or »AI« as their ever best quality = quality grade of about medium level of Continental Europeans.

Lower level was »A«, next level was »B«, and then next level was »C«, and lowest level »D«.

Please look to this topic: viewtopic.php?t=19757
