Thanks, bud. I'll give that a try.
Update from last Wednesday. Stripped off the breech ring:
Before:
After:
Internals are in pretty decent shape. Dried grease, very minor corrosion, and about a cup of coarse sand.
Here, my son channels his inner Khyber Pass Child Labourer/Apprentice Gunsmith and gently returns the bits to an acceptable state. Dental tools were key to the operation.
I note that each extractor is clearly labelled in 20-point font:
No screwing that up.
With the breech ring gutted and as light as it could get, time to spin it off. Sorry, no pix of the operation. We were pretty busy watching the Padre wrassle with the thing. But here's the back end of the barrel.
Buck naked and covered in a thin layer of grease. Nothing Freudian about that. Note the
complete absence of corrosion. Whoever tucked her in for her nap read and followed the manual, God bless 'em.
And off to the front of the gun, where the Padre again channelled the Power of the Spirits and spun the muzzle brake off.
Note the hint of rust at the muzzle. That's indicative of the best of it. The floor of the chamber area looks like the bottom of a gravel pit. She's soaking in CLP right now awaiting this Wednesday's labours. I fear she'll need something stronger, perhaps a 90mm wide ball of steel wool on a drill. Poor old thing. We'll get her running, and soon.
Onward,
Dan
