Well if anyone would know it's you Lance. How common is it to see the serial numbers on the forearm with the circle from the end of the punch around them? They also look to be upside down to what I usually see as well. Any comment on how common it is to see the widely spaced S51 marking?*As for price it's atleast $1000.00 to $1500.00 above the going rate here in Canadaat the moment.
