The Type 1 lock bar

[RCS]

The Type 1 lock bar was a replacement for the early "flush nut" on the windage knob, being easier to do adjustments and lock. Only the same problem continued as with the flush nut - the lock bar could become loose and fall off ! This Type 1 came into service use in early 1942 but by 1943, the Type 2 lock bar replaced it. Winchester never used the Type 1 lock bar.

Original Type 1 lock bar rear sights are quite expensive now and fakers have made examples by altering the Type 2 lock bar.

I have two rifles, a early rebuild with a late '41 barrel and a June '42 rifle both with the Type 1 lock barAttachment 100078Attachment 100079Attachment 100080

bob seijas,
Great info - "The long pinion was first used on December 28, 1942 on a rifle in the 1.09 million range."

Bob, where was this info found?
Is it from reported observations or from written documentation from an official source?

Thanks.

A long time ago Scott Duff, Jeff Carstens, and I bought the notebook of Walter Campbell, the foreman of Assembly at SA. He kept detailed notes in pencil, sometimes you can find gems like that. I started writing a book on it but ran out of ambition

Gosh ,Bob - Get that ambition back please !!!
Us guys really crave such info.
I know, I know, it is a SICKNESS for me!!!

I really have always appreciated the time and effort that you and others have invested for the rest of us in digging out this info and then sharing it openly.

I truly intended to pursue some kind of original research on a few aspects of the M1 Garand seven years ago when I began drawing S.S. and I had more time, but things come up and laziness sets in.

My dad always told me that I'd be too lazy to breathe if I wasn't afraid of dying. Now at my age I have to concede that he may have been right about that.

Thanks so much again. I'm adding this info to my data base.

There is a collector by the name of Brian Case, he collects data on Lend Lease rifles and I understand has over 200 data sheets, he is still collecting data.

Now data on Lend lease rifles is sometimes broken down into groups as follows:

1. the original group of 38K rifles with BNP proofs 2. rifles with the BNP proofs between the gas cylinder rings. 3. Rifles with London proofs either location

I checked a few of my old data sheets in an attempt to find a Type 1 lock bar Lend lease rifle and located the following but would require Brian Case to verify.

s/n 540534 BNP proofs rear of barrel under op rod, Type 1 lock bar s/n 539967 BNP proofs between gas cylinder rings Type 1 lock bar

Yes, I thought the solution was the long pinion, and that was staked to the type two lock bar? The first one could unscrew completely and get lost. Didn't know he flush nut could also unscrew and fall off, never had any trouble with mine over the years...good thing...

The flush nut on my original late 1941 rifle always worked without any problems but in service use they sometimes became too loose and fell out. Extra flush nuts have (on
rare occasion) have been found imbedded inside the stock) The combination tool was used to lock or unlock the flush nut

Interesting that Winchester continued manufacture of their rifles with the "flush" nut until 1943, these of course were changed out in service

The combination tool was used to lock or unlock the flush nut

That's right, I had the original tool and remember the forked end now...only applied it to see but never used it.

I've told this story before but it's interesting: when I first talked my way into the Numrich parts warehouse one of the bins I looked in was sight pinions. I took two of the early short ones, but didn't find any numbered ones. However, the bottom of the bin was covered with loose flush nuts, must have been 50 of them. I took three and left the rest. When it was time to pay, they had no idea what to charge for them, so said "Oh, just take them, no charge."
