this neverending fake discussions are rather boring. The shown fakes get simpler and simpler - there is no limit anymore.
1) this cigarette case pattern is a typical British (England) pattern and nowhere else seen or made - n o t R u s s i a n!
2) the monogramms are in Latin not in Cyrillic and when you look close: they are older than the Polish inscription = the Polish inscription was added later!
3) the 24A is total sensless when you know the history of the different Artels and what they fabricated in highest quality! They never used coloured glass cabouchons.
4) the kokoschnik mark is a fake - where the eliminated English marks have been I do not know - may be it is only plated - your photos are not precise enough.(admin edit - see Posting Requirements )
