MR, I remember those Siamese Mausers. I saw a few that had been converted to 12 gauge shotgun.
Remember, too, that during the 40's and 50's, Springfields and Enfields were available cheap thru DCM, as well as other surplus outlets. M-1 carbines, too.
Not to mention all the 98's and Arisakas that came home in duffle bags.....
And Carcanos...at one time- I'd guess late 50's-early 60's, you couldn't give away all the Carcanos floating around.
Or selling for 12.88$ with scope
