Winchester ReUsed Serial#??

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have this Winchester carbine and the serial number is in the first block 1,27X,XXX. However, it appears to be a type III receiver, and if I’m reading things correctly, it should be a type type I.  I also have purchased but not picked up yet, another Winchester first block serial number 1,21X,XXX that from the pictures appears to be Type 1B receiver as I can see a whole, where the slides stop pen engages. I should have that rifle here next week if not by the end of the week and I will get some more pictures of that on here for show & tell. Can someone tell me what I am looking at and if the receiver is a reused serial?

	what is your source? Type 1 for Winchester only has the rear slide guide way notch, Slide stop detent and a slide dismount notch. Type 2 has front and rear slide guide way notches. The slide dismount hole is absent both have the spring tube or two piece receiver Type 3 is a deep hole one piece receiver the type 3 receiver shows up in the 116xxxx range which overlaps the type 2 range. in the early range the left rear detail was 9/16 " in the 124xxx range to the end of the block the left rear detail was reduced to 1/4 inch Spring tube receiver details https://www.uscarbinecal30.com/forum/spring-tube-receiver-indent-detail_topic3973.html for the left rear detail refer to the clubs datasheet. https://www.uscarbinecal30.com/forum/data-sheets-newsletter-back-issues-indexes_forum42.html the video section has links to filling out the data sheet with info on each item. such as what the rear left detail is/

	I’m using the comprehensive Guide M1 Carbine by R.C. Larson. Check The link again, I uploaded the two pictures from the references in the book as well as a close-up of what I was talking about on the gun I’m buying. Let me know what you think. I appreciate your feedback.

	Sorry, there are two pics of receivers now. The one with only the notch is the 1.27mil serial and the one where there is a hole is 1.21mil serial range.

	I've seen other WRA receivers in your serial number range (1.27M) that have the integral deep drilled spring hole, so I don't think it has to be a reused serial number.

	112xxxx i would expect to be a type 2 receiver. all Winchester receivers had the hole at the back of the receiver. look at your 127 and notice how a bushing is crimped in place, though something looks off in your picture, may be the lighting. Recommend CCNL 336 which has the Winchester first block update late type 2 receivers did not have the hole going through the slide stop detent on the right horizontal rail. this changeover appears to begin in the 112 range Edited by New2brass - Dec 31 2025 at 6:26pm
