So, I acquired this Weihrauch 50 for Fathers day. At the time, I could see a couple of issues, but I didn't think they were a big deal. I was/am unfamiliar with the brand/ model, but who doesn't want a German gun?
I brought it home, dug out a box of. 177s & proceeded to get busy with it.
The front sight was loose, wedged in place with a piece of beer can hanging out the right side. I took it off , & stole a scope from a 760 that doesn't get shot much.
The breech seal most closely resembled old peanutbutter & may have been rubber at one time. A pair of o-rings will serve for now, a skinny one in the back as a spacer, & a fat one in front to seal.
From the 15 yard target off the back porch I was getting 5 shot groups that were easily covered with a pie plate.
After running through every different can of .177 pellets in the house, & discovering it didn't like any of them, I decided to open her up, & see what was going on in there.
First stop, the interwebs to see how this thing comes apart, & try to limit the surprises.
Disassembly starts easily enough, & the first thing I noticed was that the two .006" pivot washers were missing. That might have something to do with those groups.
The next thing I noticed was that the power plant didn't look anything at all like the videos I just watched. Confused, I go back to the interwebs & eventually determine that this gun has a HW50 front end, & a HW55 back end. It was the lack of a safety that led me there.
Disassembly can continue now, & it comes apart exactly as shown. The mainspring is well bent, & the piston cup is leather, & the grease has hardened to a solid mass. After agonizing over the cost, having the guy from Arizona not willing to even take my order, & not being able to make contact with anyone at pyramid, I ordered the whole kit from Vortek. It should be here in a few days.
All the parts are cleaned, the piston is polished, it is quite undersize, so that was probably unnecessary.
