I sold the Ohio-made Turkeyslayer with 24" barrel and choke tubes. The parkerized short-barreled Ithaca 37 with bayonet attachment was sold years ago. That was no military gun but was either police gun or one of the ones sold to civilians in late 1960s. While serial number was in Vietnam era military range the gun was clearly NOT shipped to a military depot as it lacked government inspection marks. The one with government acceptance marks is actually ca. 1942 field grade gun with 30" barrel and full choke. My primary hunting shotgun is 16ga self-loader with IC barrel. The only person confused on this board is you.
