I still have one more Western Auto to put together, and two more 1st ver. 760'sCan you tell I like Crosman pumpers?
Not sure where I found the info below, maybe here on GWTAG! Perhaps it will assist someone creating an official list, although as mentioned, between the manufacturer using up old stock, and owners swapping parts, there are sure to be variants of variants!First variant. Wood stock and grooved wood forearm, brass bolt, smooth bore 1966-1970 (These smooth-bores shoot really well with pellets.)Second variant with styrene stock & forearm & scope mount groove, brass bolt.

Thanks for sharing your variant/model lists and descriptions. I have most of the variants and a Revelation I restored. I've found the same on missing detent springs and gate spring to hold the BB's. FWIW, for the little detent spring, I put a small o-ring on the end that fits in the base hole, to wedge it in securely when putting the receivers back together. Also, a piece of black electrical tape holds the BB loader spring in place until together, and you can just slide it out. Perhaps you are aware of these tips, and have your own. The Crosman service manual mentions whether the rifle has an earlier "gold" trigger, or later plain trigger. Thought I'd share for anyone reading this new to 760 rebuilds.Some time ago I posted images on the restoration of the Revelation. It had similar rust issues, so I removed all the rust with sand paper and steel wool, and re-blued it with some Birchwood-Casey paste. Turned out great and still had the hooded front sight. I cleaned the barrel with brake cleaner, then rinsed with very hot water, and dried. Then I applied the bluing paste and smeared it around until the reaction was done. Rinse in VERY hot water, and dry with a couple of lint free paper (blue) shop towels to avoid finger prints. Re-apply the bluing while the barrel is still hot, as it helps the bluing reaction. I had to repeat this about 12-15 times, but each cycle only takes a few minutes. Apply a bit of light oil, and your barrel will look brand new.For the earlier brass bolts that are known to wear and give blow back in your face, I've built them up with solder, then honed down to get a good fit. The solder is soft enough, it will actually create a little shoulder to seal the breech. Hope that is helpful.thanks for the tips and tricks on rebuilds. I use regular scotch tape when I install the BB retainer spring, and pull it out before the receiver is tight.
Hi, John,PM'ed you a bit ago about the bolt, but now I've a question about these 760's. This looks like the place to ask!I have a barrel/pump tube that came in a pile of stuff my buddy dropped off the other day.I have never seen this barrel before, and wonder if it's an early one. It is attached to the pump tube at the breech end with a screw. And maybe a bb feed hole in the top of the barrel?

I'm sure there are others that use that type of mount.
It looks like a 1st ver. 760.Are you going to rebuild it?
