Colt 45 barrel in my Ithaca Question???

HI Guys I have a Colt 45 auto stamp on top of barrel by ejection port in my Ithaca 45.
I read somewhere colt supplied Ithaca w/barrels. How can I trace if it's original or not?
Thanks very much!

If the stamp is on the top of the barrel, the barrel is post WWII.

Thanks John, that's what I thought!

Plus, of course, all WW2 barrels were blued.

My guess is that your barrel is nickel plated, which means that it is a Colt commercial barrel. DOD bought a bunch of these in the early '60s after they ran out of WW2 barrels; my DCM .45 came with one of these.

I do believe this was a DCM pistol, not sure though. The barrel is parked olive green. Nice park job, shiney and unused. Not the dull gritty repark you usually see. That's why I thought it was original to the gun, as it all looks unused.
No rebuild stamps etc on her.

For most Ithaca production, it would have been shipped with a High Standard 'HS' or a Flannery Bolt 'F' barrel. Very early initial production could have had a Colt Type 5 barrel, or a Springfield Type 14 barrel.

If you need an original barrel for your Ithaca, I may have one.
