I just bought an EG Mak which has what I assume is the date to the right of the serial number "EWXXXX 64". When I took the grips off I found the following number sequence stamped on the left handle base, '62666'. My guess is that this was a reconditioning date, probably before it was put into storage and eventually finding it's way to the good old USA. The bore looks new and the firing pin has been replaced (still bluing over the tip of the pin) so this is the conclusion I draw. Anyone's input would be appreciated.
