Indeed,the same mark appeared in both years:
Клеймо ЛЮ7М - 1967 год
Клеймо ЛЮ7 М - 1957 год
1967 was 50th anniversary of 1917 revolution and enormous number of items commemorating the revolution was produced by that factory, so everything I saw was made in 1967.
Did not even think of 1957 until Qrt.S pointed it out, which led me to visit several Russian sites to confirm Qrt.S is right.
I have no explanation for that.
This raises the question of faked Imperial Russian silver.
Good to know: hundreds of thousands, probably millions of enamel badges were made in Soviet block at the time, practically worthless.
And the enamel was of rather good quality,by the way.So what they did after the collapse of USSR ?
They concluded it was more profitable to fake Imperial Russian enamel.Then China and India joined for full confusion.
Many factors contributed to Imperial Russian enamel to become fashionable, much sought for, lucrative and expensive.
Although, to be honest,except for several reputable makers in Russia (mostly Finns working for Faberge), much better enamel was made in Scandinavia,Britain,France,Austria,Pforzheim...
