U.S. WWII Ithaca Model 37 Trench and Riot Gun

I respectfully request where to locate information concerning shipping records of a WWII Ithaca Model 37 Trench and Riot guns. Could a Shotgun World members provide shipping information/records for my Ithaca Model 37 Trench Gun, serial number 61501 and a Ithaca Model 37 Riot Gun, serial number 61422 that I may be purchasing? If this information is unable at this point, could a member point me in the right direction. Your help is greatly appreciated!

If you just hang on a minute, there are several that can and will help. They just have to see this post.
