Hi!
Sorry rukivverh that the discussion got to another direction but I hope you also learned something new.
Well I guess we don't get further than this. You vote that it is a fake, I have to say I don't agree on all your points Postnikov but there was one point that I agree on which could mean a fake. Anyhow I don't see that the marks would not be real but you have an advantage I have only been studing russian marks for 12 years not 20 years.
I disagree on the effect on polishing. As showed in my example of an english spoon the letters can be crisp but the edges bent. If the edges would be crisp I would be more concerned. I am sure you know how soft the silver is so you can easily bend the spoon stem where the marks are. I agree that the letters etc. can many times be also damaged but not always. I also made some comparisions of the city mark on other city marks from the 1890's and consider them to have similarities.
I don't know the marking policy of the Nemirov-Kolodkin firm, meaning when the AK was used and when not. I just also wanted to show that the AK is without a dot.

Well this was an interesting discussion, at least I got some new information. I am sure this didn't anyhow change your view Postnikov.
Regards,
Juke
