Hi,

A friend bought this Sheridan Model B Sporter recently from the USA.
I am going to try to make it work again.
The pump cup doesn't seal in the tube. A friend advised to soak in transmission fluid stop leak.
Hopefully that will work.

I would like to "get into" the valve.
Mostly out of curiosity, but probably because it needs new seals.
There's no info on the net on how to do this.
I guess a special tool is needed to unscrew the valve nut?

Here are a few photos. The gun has seen some life, and I think the barrel blocks have been re-soldered. That might be the reasons why all the paint (B's were painted, A's were chemically blackened) is gone.

Cheers, Louis
