Help identifying a soviet set

Hello,

I have a chess set, which I believe is from 50's or 60's USSR. I can't pin exactly what it is though, the king crown is unique from other sets I find online. Most soviet sets have a teardrop shaped king crown, however mine is more diamond shaped. I attached two photos, one being my set (black pieces), and the other being a more typical set (the pictured example set is a reproduction I believe but still same idea) from what I believe is to be from the same era. Any information is most appreciated.
