I have a copy of a Sears, Roebuck catalog of military goods from 1917 and believe it or not, they include a Colt machine gun. I don't have it with me (I must start carrying it with me for times like this) but the price of the gun and tripod was in the thousands of dollars and that was in 1917. In comparison, a Colt pocket auto or a Colt Police Positive revolver was something like $20 or $30. No Government Model listed. Why anyone thinks the price would go down if they were legal now is hard to believe.
I also tend to look hard at things were "millions" are mentioned. I realize a million isn't what it used to be but For there to be millions of automatic weapons in circulation from war trophies, everyone who served in France would have had to have brought one back. And I also wonder about "millions" of supressors.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
