Anyone see the wire buttstock? Maybe under the M3 in the box?

The original finish as applied to MP40 SMG's and MP40 parts produced during WWII was a hot dip salt blue prior to the late war bonderizing process. Bonderizing is similar to the US military parkerizing process. Some of the bonderizing was tinted with color/contamination or was clear. Even late in the war the MP40's that were having a bonderized finish may have some small parts that were blued. Subcontractors used whatever parts they had to complete guns so there are some strange combinations of parts on some original MP40's. Have seen original late war MP40's with early model parts as that what was left in the parts bins. Most MP40's that were brought into the country as parts kits have been rebuilt or repaired by the host country many times. Norway used the MP40 for tank crews up to the early 1980's. The original MP40 receivers were stamped, formed and then welded together unlike the MP38 receivers that were a machined tube. Whatever finish was on the metal after forming was the finish on the metal after being blued. No parts were brushed, just the natural metal finish.

I have a barrel wrench for the TSMG that I can let you borrow if needed. I sent you a long email with some information on the barreling of the TSMG. Hope the advice helps.

Everything looks great!!!!
