My JM kit came in yesterday, so I've stripped the old HW 30 down.
If you've ever read any of Robert Law's classic Air Rifle Headquarters literature, you know his idea of a "tune" (or "accurizing" in ARH-speak) was to pack AN ENTIRE TUB of moly grease into a rifle! This one seems to have received such treatment...everything inside is mummified in the stuff. It's gonna take a while to de-muck it, but the old lube looks to have been a good preservative at least.
I should have taken a pic of the stock inletting before I wiped it down...yuck. It looked like a coat of silver-grey paint.

Funny, I just cleaned out an HW35 where the piston was also entombed in Moly and some sort of white lithium grease. The barrel is wrapped in black shrink tube, so possibly another one of Robert Law's accurized guns.
