Semi-Auto Thompson Stock Adapter...

Thanks Doug, they were out, last time I checked.

John, they don't just "bolt right on". The butt stock mounting structure of the lower receiver needs to be modified by milling off a bunch of material. The approx. 1/8" tall remaining structure is then drilled and tapped to receive the adapter plate. The adapter plate is pretty simple, so I plan to make my own; the most demanding aspect is to accurately locate the notch for the latch on the stock. Some curves/lines on the bottom of the receiver also need to be changed to make the installation true-to-original in shape.

I thought I was all set to go, armed with a copy of the blueprint of a 1928 and a removable 1928 butt stock with all its hardware. The butt stock arrived, but I found once cleaned up and all the cosmolene scraped off, that it had been exposed to water at one point during its storage and it was rusty on parts of the structure that were not exposed, where the water had seeped in. In addition, the furniture had absorbed the oxide and is stained. This latter part is my problem, as rust stains are very difficult, if not impossible, to remove from wood, once established.

Anybody know of a sure-fire way to bleach out the danged stains? (Oops, didn't mean to hijack your thread!!)

No Hijack since I got my answer from Doug.

I would use electrolysis for the rust on the metal, and would likely try a full strength Lime-Away soak for the rust stains on the wood... After all, you've got nothing to lose... the only other alternative would be new wood ($$$), or a lot of sandpaper and elbow grease.
