I have seen guns in this condition fire when the magazine was removed; I think Got Uzi has it right.

TT95: I have a 28 receiver nose- email me.

After a lot of careful consideration during a troubling last couple of years I decided that a review of was in order, and determined that the current queue was too large. I therefor chose to advise the latest entries that it was unlikely that I would be able to service them, believing this was the honest and decent thing to do. I did not say that I was semi-retired, but in truth, with age and time, I have slowed down a bit. If you did not receive the notification mentioned above then you are still in queue. I’m sorry for any confusion I may have caused, and for any unfulfilled expectations.

Yes, still available. Contact at: p-k at q.com

1928 buffer discs are $7.50 post paid Thanks :-)

Bob, i applaud your willingness to do the research tests of the various systems, i think this is long overdue and we are, today, in a better position to accurately accomplish it than ever before. I strongly encourage you to use accelerometers and strict scientific methodology. I look forward to seeing the results. From a strictly empirical standpoint, firing a 28 next to a M1 would not lead one to believe that the 28 bolt is striking harder than the M1. Standing by...

Really, really bad idea. The TSMG and M1 are actually very different guns. The 21/28 receiver is designed to use the Blish lock, the M1 not, they don't mix. WH receivers with bad slots will crack from normal use because the lock can't do its job, eliminating the lock doesn't solve the problem, it exacerbates it. IF i recall correctly, the Richardson set up was for blank firing adaptations, not for use with ball. As others have said, we've been down this road before and it doesn't end well.

cbmott; I had no intention to be either rude nor condescending, just factual. I'm truly sorry i did not more clearly present my thoughts. Tact is not known to be one of my finer attributes. :-(

If you are going to post photos, you could have wiped the grease off so the uniform finish was truly represented.

I’m not in the parts business, but when i can’t get what I need I’m forced to make it. About 10 years ago milled grip mounts dried up and I produced a batch, then the Russian cache was discovered and we have been in Thompson parts heaven for a while, but that’s coming to an end and it’s no surprise that milled grip mounts are no longer readily available, so I’ve produced another lot. These are made to the 1920’s prints from the correct carbon steel and properly hardened. They are suitable for live fire applications and not just display purposes, being as good as or better than the GI parts to which we have become accustomed. Price is $67.40 plus $10 for priority mail shipping. 1st class is available upon request at a slightly reduced rate. Cash, check or money order to: Diamond K 1390 E. 7th St. Delta, CO 81416 p-k at q dot com Thanks David for the forum

If anyone has a USGI milled Grip Mount laying in the drawer and would rather have cash, I need one for a current job. Price will depend on condition, but all parts are worthy of consideration. Please email me: p-k at q.com

The notches are from cutter run out; just plain sloppy machining, but in most cases they don't affect function. They are common throughout WH 28 prodcution.

To many to mention, i don't have time to write a paper on it, as interesting as that might be.

Your unmarked bolt may well be a WH, in which case you do not want to run it; cut it in half.

Direction is as viewed from the top rear of the gun, as it would be fired. The pin is not a "standard" diameter, for whatever reason they chose to make it .115". When i need to replace them i use gage pins for stock.

The hole in the base is undersized on the left side; this is by design to provide a press fit to keep the pin in place when assembled. The hole on the right side and through the sight ladder is sized for a slip fit so the pin can be easily inserted while the sight is assembled. Always remove the pin left to right and reinstall from right to left.

The old fibre buffer disks are all pushing a century of age and are not ‘off the shelf’ anymore, that is why new discs are made. Polyurethane is an excellent material for the reasons Laurencen listed. If you look at the photo provided by Ville28 you can clearly see where cracks formed long before it ‘disintegrated’, it has been my experience that the material will crack and not crumble when/if it fails. The part depicted by Timkel was not made of polyurethane; I examined these for him and can state that definitively. The buffer disc is there to isolate a metal to metal hammering and prevent damage to the steel, it is a sacrificial part and should be inspected with regular cleaning and replaced when cracks become evident.

It's like shooting 454 in your 1906 SAA: Dumb idea, you'll break it.

The actuator blueprints are available; why not use them instead of reverse engineering (which is always second best)? If you are going to invest in production you need to insure that your parts are to genuine dimensions & tolerances.

The GI chamber is ~.01 larger diameter at the rear

Any contact information would be appreciated.
