I brought an old crosman140 from an antuques shop a couple of months ago, but ut was in a bit of a state, but nothing I couldn't fix.

I was having a little trouble with how things were put together, so I brought another one from here, hopign it would have a full safety catch.

All there seems to be is a half circle that you couldn't turn with your fingers.
(Looks a bit like a "D", and is about 1mm high & next to the trigger)

I have a feeling that there was a lever that sat over the top of the "D" that people loose.

Does anyone know what they really look like.....or even have a piccy?

Cheers,
Elliot
