I bet this headstamp would, if it had gotten around to collectors, become confused with the M DAM M headstamps made in Brazil for the Director of Armaments, Ministry of the Navy!
Its nice to see all these great headstamps - keep them coming - but it has its discouraging side too when one knows that they basically will not be available to most collectors. It is becoming increasingly impossible to even begin to keep up with all the new rounds coming out. They come and go before most of us even know they exist, and it seems that not only every country, but every little agency these days must have its own headstamp. Property control or just plain ego? I don’t know which.
