While my main interest is identifying the name of the pattern, I’d also like to know a bit more about the brand itself. There’s a small mark, set in a square, which I wasn’t able to photograph because my phone can hardly capture such fine detail, but it looks like two “C”s with a scale in the middle. I’ve seen many photos of this hallmark — from what I understand, it was used until 1935, but do you know approximately from which year it started being used?
Thank you very much! I appreciate any information!
