Thanks to Fred for his nice words, but certainly is Fred expert on that area, as we talked in BCN time more about this stamps, i personally found this type of flower stamp only on Mundlos bayonets when i am correct, and mainly on not accepted rejected production, by magnifying glass should be there in flower visible of older WaA proof probably. Anyway the serialing of parts under grips or the locking nut could be interesting to see,b.r.Andy
