There is one of these for sale on Armslist (Texas) which has to be a scam for the price asked, but it brought up a question.
Since a lot of these were destroyed, how many are estimated to remain?

Also since the scammer didn't show a pic of the U.S. mark or model 56 stamp in the crane, could the picture be of a model 15 that falls in that serial number range?
Inquiring minds and stuff.
