Hi guys, I'm restoring an old standard although I don't know how old it is as yet? I'd like to know what sort of power these things should have.

It's .177 and it has the push button underleaver with numbers on the trigger block starting with the letter c I believe but will double check tommorow, as if love to know what sort of age it was made too?

Any help much appreciated as always.

Really looking forward to shooting this old girl.

Thanks
Daniel
