I managed to find one that was still in the brown wrapper, what a load of cosmo in this old girl.
The bore was packed with it as well as every inch of the rifle, the front sight had a big gob of that nasty stuff and was totally covered.
I took a heat gun and sweated the cosmo out and wiped it up with a rag as it liquified.
To get it out of the bore, I dumped boiling water through it and it came out coffee colored water.....ick.
I bought a can of carb cleaner and the rest of the rifle was done, the bolt was packed solid with 60ish year old cosmoline.
I cocked the rifle and tried to fire it, instead of the firing pin dropping and making a click sound, it released and slower than molasses in January.
A total disassembly of the bolt and a bath in carb cleaner with a little coaxing with an old tooth brush and I have a working Yugo M48 8mm Mauser.
The stock sucked up a couple coats of Boiled Linseed oil already and the teak stock looks 100% better than it did out of the wrapper.
All of the numbers match including the stock, now if the rain would stop long enough to get to the range.
PS, I have a couple of pics of the M48 during the unwrapping, if someone wishes to post them for me, email for pics at deerslayer@shaw.ca
