  1. That's a level of restoration I would not care to attempt, especially fabricating replacement parts.

    1. The most gunsmithing thing I ever did was pry the firing pin out of a Zastava M57 pistol. The gun came slathered with cosmoline, and I thought I needed to take it apart as far as I was able. It was a hell of a job getting it out, and a hell of a job getting it back in (if memory serves, it was Mrs. Paco who finally got the thing reinstalled). And I didn't even need to do it at all. As I found out when I bought a similar handgun (a Zastava M70 pistol), all you really have to do is field strip the gun and submerge it in mineral spirits for an hour or so, and just depress the firing pin several times to let the liquid work its way in.

    2. Yeah, cosmoline is funny like that. Try degreasing a rifle stored in that stuff!

      I've changed stocks and added accessories, like grips, new sights, heat shields, etc, but the closest I came to actually gun smithing was modifying an SKS to eliminate slam fires.

      I found out the hard way that the SKS has a floating firing pin, i.e., no spring. That means the pin rattles around inside the bolt.

      Normally, this is not an issue, but a lot of the old Soviet ammo has cheap primers, with thin walls. Thin enough that the firing pin could set off a cartridge, without the trigger being used, when the bolt slammed forward to rechamber a round. Multiple rounds could be set off with one squeeze of the trigger ... ... and you never knew when that might happen.

      Not good. Not good at all.

      After some research, I found a modification kit which added a spring to the bolt. It came with instructions, but I had to disassemble the bolt, normally a task for an armorer or gun smith.

      After that, no more slam fires!

  2. I got a Mauser from Mitchell's Mausers made somewhere in former Yugoslavia in the 40s and stored in cosmolene since then.
    It was easy to clean, the hardest part was the bolt, but a few minutes with some Qtips and CLP and it was clean as a whistle.
    It looked as though it was made yesterday, all matching numbers, even the bayonet.
    Of course, the bolt is the only moving part except the sights so it was not a problem.
    I see a lot of hate for Mitchell's Mausers online, but that one was perfect.
    I got a German one with Wermacht markings not Nazi, that was advertised as rough. They got those from Russia, not matching numbers, but they said they were rough. I got what I expected.
    Also, since they got it from Russia, I figure Germans used it to kill commies then Russians used it to kill Nazis. Kinda cool.
