Looks like a good restoration. I rebuilt probably close to 8 of those type guns, mostly 747 and 777, I know 3 of the 777 models, and I want to say 4 of the 747's and one in .22 cal. Two of the 747s were for my son and grandson, so that they can have matches at their home. I replaced all of the valves, and seals using polyurethane seals, I got the kits from a seller on ebay, and they used a series of I think 5 split teflon rings to use instead of a foam wiper to hold oil. Seems to work well, they fit just slightly loosely together in that groove behind the O ring for compression and the space between them seems to hold a good bit of oil

My original hasn't failed as yet. It's funny that when I put the original valve in this one it came to life.

so the pistol is easy to work on the
now the pistol need to be cock and that takes the pressure off the valve and it closes and after that you pump the gun
would i dry fire the gun i see no reason not to
so my question about the tube was because you can't assemble the pistol that way the cocking handle has to be in place and with that the front sight that the barrel slides into
if you have trouble just message me i have 8 or 9 of these pistols

Its done.
The new valve from JG was not functioning properly in the valve body. If you backtrack and watch all the videos you'll see how it went.

I found the old original valve in the parts that came with the gun, and put that one in for the repair

The symptoms were no safety spring, but had a new one in the parts. Couldn't release the air completely installing the original rather than the JG fixed that.
Thanks 👍

I have two valve bodies

This wouldn't fit my barrel. It is Keyed with a flat top. My other valve is round matching the barrel.

Any clue as to what that is about? Maybe the 747/777, use the keyed valve body for the Walther barrel?
The 717 uses the round?

No Idea, It has been a couple of years since I did all of mine, and don't remember removing the valve body, also never worked on a 717.

there is no reason to remove the barrel from the valve at a rebuild so i don't know
of course if you thought you needed a new valve was and you bought it without the barrel
the valve pictured has paint overspray on it and would need to be cleaned at some point if used
it is a who know deal
the pistols were made for so many years it would be hard to say if that changed the barrel to valve interface and there is no need the clock the barrel

there is a thread of a very talented airgun smith that had a problem with a leaking valve and he did everything to fix it and he gave up and bought a new valve and barrel as a new complete part and the problem was solved

i have told people before that these are very easy to fix and work on
but when they leak you can you break out the bowl of water and see where the bubbles come from and go from there and sometimes you can't fix then without a new valve and barrel and that is a problem there are none
old valves and new valve stems have a large chance of not working also

so, they are easy to work on UNTIL THEY ARE NOT
parts are disappearing fast and don't break your rear sight, those are all gone also
and one other thing if you see some parts and you have the money buy them
