Just another tip Gary, when you go to put the two small pins and spring back in for the safety, the pins have a flat end and a slightly conical end. The conical ends go either end of the spring, I found if you put them in the other way you can’t compress them enough to slip the little pin in at the end.

Also, once you have them in, before you put the small end pin through that holds them in place, you have to push the cocking lever back a tiny bit more for the bottom pin to drop into place.

Hope this helps, sorry for the phone number cock up ( insert red face here ! )
