The frame bears the Colt logo. There must be some Colt experts on this forum that can shed some light on this.I once had a firearm that I bought directly from the manufacturer. It had a second "A" stamped ahead of the serial number and the owner of the company explained to me that the initial run of receivers had the first 500 serial numbers duplicated. So, they had to take half of them and restrike the recivers to add an additional "A".
If that was a wartime frame made by one of the many contract manufacturers it is possible that there was a serial number overlap, that was then restruck, but that is kind of assuming a lot.
Here is the Colt logo, does it look faked?there are a lot of colt fakes out there where people try to take a common reciever like a ithaca and try to fake a colt serial to mate upp with a colt upper to sell for more money.
its obviously a pre-68 so serial number isnt technically required depending on your state. but it does have an altered serial number and thats against fed rules regardless of date.
if your interested in buying it for a cheap price, less than 450$, contact colt and see what they say about it.
personally i wouldnt touch it.
Even during war production colt didnt screw up stampings. Some makers like ithaca hand stamped serials so there is slight variation from gun to gun. Colt did and does all their stampings by machine using jigs so each one is the same place and same type never double stamps on logos.Here is the Colt logo, does it look faked?
