After hitting the "send" button for my Sharp book yesterday (to the man who will do the layout), I decided to celebrate with a bit of tinkering.
4 guns to work on:
2x BSA Light Pattern, Crosman 622, Sharp Innova.

The Innova was lovely to work on. An early example, without transfer port tensioning screw, but with 3 screws through the trigger guard.
The stock needed a bit of CCL oil, and I adjusted the trigger. On test firing, I could feel quite a bit of air escaping from the side of the breech, with my usual four pumps.
On closer inspection, the breech appears to have a crack. Probably from the valve stem hitting the rear of the breech since the eighties. I have a feeling that the crack has worsened over the last few shots.
I wondered if there are fixes for this problem?

Cheers,
Louis
