Remington Chrome Moly barrels
 

In the course of doing a PGCA letter on my Remington-Parker Trojan 20 gauge #238172, Chuck Bishop identified a notation for Chrome Moly in the stock book for this gun. The barrels have the normal to rib saying Trojan Steel. This is a Meriden gun but post Remington commencement of production by a couple thousand guns. The Remington date code is BE for January 1936.
There are stampings on the same left barrel flat as the date code of "M O" as shown in the picture below.
Has anyone seen these marks before and if so can they furnish me pictures and data(serial number, Remington date code, rib markings)? Email: george.m.purtill@snet.net .
And of course feel free to post to this thread.

George, do the barrel flats have the Remington stamp for Chrome-Moly?

Dave- what do you mean?

No Dave, just the MO and no other stamps referring to barrel steel or any of the other "meaning unknown" stamps. Suspecting the MO is an early designation for chrome molybdenum... certainly a distinct possibility.

You could be correct Dean, but I have my doubts. Chrome Moly steel alloys predate these guns by many years and the AISI designation of CrMo goes back to the teens.

I'm not arguing the hat point Edgar - however, this Trojan may be one of the very first Parkers that Remington applied chrome-moly steel barrels to. Remember, there were plenty of barrel sets in inventory when Remington bought the Parker Gun Works but Remington had to start making barrels for Parkers sometime and if the supply had run out on 20 ha. barrels around the time this gun was made it only makes sense that they had to mark them somehow and this may be such a gun.

Edgar-I don't disagree with your metallurgical point, the issue as Dean says is when did Remington start using THEIR CrMo barrels as opposed to whatever PB had in stock and was there a marking of same on the barrel flats.

Aside from the Trojan Steel rib roll stamp, Parker Bros. Had always stamped the right barrel flat OV for their Trojans in all gauges and all barrel lengths.

We all could speculate forever but my guess is that the MO is an in house stamp used to identify Chrome -Moly steel. JMHO....

I agree Dave.
Now the question is........ does anyone else have these stamps on a post 236,000 gun?
