Makes you wonder what the rational was for changing the Inland logo from horizontal to vertical that they thought was important enough to Change this one.

Bill,
Yes that is why I asked about the comma thinking that it may have been an earlier scrapped receiver and then reused with a later serial. Whatever the case it is interesting.

 No comma. All NPM 'U' and all UN-QUALITY receivers that I've seen have
the comma on the front ring. Quality H.M.C. carbines also have this
front ring comma up to serial number 1621877. QHMC carbine 1633386 and
beyond do not have the comma. Somewhere inside this range of serial
numbers is where the comma went away. Newsletter 380-19 has a short
blurb on this "comma question". SF, Bill

Yep OAMAAM68, that is an interesting QHMC. Wonder if it is possible that that was a re-used scrapped receiver. Does it have a comma after the 30 on the front of the receiver?

cool--never seen a QHMC with that issue from serial machine before--it would have been around Oct of 43--is about when Un-quality started producing--maybe they crossed it out-sample receiver--no idea-just a wag--I have a NPM buff out Un-quality so anything is possible

Quality Hardware & Machine Co. 1641290 in original finish with a
line through the Quality H.M.C.. This is one I’ve had a while. Thought at first it was intended to be a line-out; but, since I never found where QHMC sent line-outs to other makers, I concluded the line through Quality H.M.C. was a stamping machine error when the SN was applied. Buffalo Arms 8-1943 barrel. Has a Type 1 square S -- never been off dovetail; both leaves are notched.  |

I have a T-1 band swivel that is unmarked except for a stamped line or crease in it.
This band and swivel came from a crate of de-milled barrels and receivers that were de-milled during the 1960s and had been sitting in the original crate ever since, so I have high confidence that it is genuine. Maybe it is just some kind of artifact that was left by the stamping process, as does not appear to be a purposeful stamp or marking of any kind. The photos and lighting make the coloring look very silver in color, but in person, it is a flat gray parkerized color. Anyone ever seen this?    |

This one is on eBay right now. Wonder if it is just a mark in the carbon film from the gas port hole and recess in the front of the piston chamber? This one has a similar mark, though not nearly as defined.

@ 1st M1 88: That is an interesting band. the C does not look
symmetrical, though it may be the angle the photo was taken. What is it
on? @tenOCEE: I misread that the R was on top
of the extractor, which is a later feature. Yes the overstamp has been
reported on the inside and not an Underwood extractor. Evidently not a
recorded transfer. @Jack: Odd that the C
is not carbon fouled. I figure the etching would grab it up. Do you
think this is specific to a particular barrel manufacturer? |

Hmmm...wonder if it signifies a manufacturer or maybe a different material, like being coated with chromium or made of chromoly? Aren’t some barrels coated with chromoly? Maybe they were experimenting with something?

How about a piston with a "C" etched into the fat side?

On the extractor portion of the discussion, it wasn't an Underwood piece, but I never bothered to check WB until now for transfer info. It's not listed as a transfer. So the info must be on a COM layout, a newsletter or just between knowing collectors. The sear isn't an early transfer, and I see it's listed in WB.

checking COMs there were several springtube RO carbines, all reported as having an R sear.
Authorization for a transfer of sears from Underwood to Rock-Ola was approved in September 1943. Then again that is the only know transfer of sears between the two

I purely took his word for it and assumed it was so early of a transfer that it was limited to the earliest. So, there is room for error in that assumption.

I found an extractor which had a similar small overstamp. Turns out that is correct for a very early Rockola spring tube and I quoted a guy a price of $85 for it about 7 years ago. The buyer was very happy to get it. Very rare in the case of the extractor.
