1937 blueing process

thor, when they swithced the blueing process in 1937, did they still blue only the outside and leave the inside white? or was it just completely blued over for speed?

When they switched to the salt or immersion bluing they blued the entire piece that was being blued, in the case of a barreled receiver that would include the inside of the bore and inside of the receiver forks, everything. It is hard to plug a bore that is being immersed in 300 degree F liquid for half an hour (actual time and temp will vary due to chemicals used), actually the bluing adds some bore protection as well. In rust bluing the max temp is 212 degrees F. I always plug the bores on rust blues but never with salt bluing. Remember als that if a 1937 weapon was before the "t" block is should have a rust blued finish if probably done. It appears from TRL, Jan Still's excellent reference that from the 1936 "n" block Lugers to the time when the 1937 "t" block switched to salt bluing, that this range of Rust blued Lugers did NOT have the interior surfaces polished as before, an important fact to remember. The muzzles on post 1937 (salt blued) Lugers were left in the blued state when issued. I am sure that upon firing them, some of the bluing is burned away and the holsters and other adjacent objects may have also worn some of it off. Thor

Thor and others,

I once had a 1911 reblued (maybe 30 years ago). Reputable shop and great job--but they blued everything. Dummy that I was, I didn't hold the small parts that I would have preferred in the white.

Needless to say, they blued the barrel and bore. Not to worry, the bore blue didn't last 100 rounds. Today, the bore is shiny and bright.

Great information Thor. I checked my 70's Mauser Luger and the inside of the barrel is blued. I have fired this pistol many times and the inside still remains blued.

Thor, with the information about bluing on the inside of a barrel, you changed my life. <img src="graemlins/crying.gif" border="0" alt="[crying]" />

That information is too good. <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />
