I've got right here, according to the receiver markings, a Model 303 Super - Suhl - Haenel - Kal 4.5mm . It was given to me by an old friend years ago for me to use in teaching my boys to shoot. It had been cut down (stock, not barrel) to kids' size and had about the best trigger I've ever used on a springer. My friend was an old gunsmith and he'd fit it up with a Weaver scope base and rings and a Bushnell Sportview 4X32 scope. It has put in good service over the years but now the sear will no longer engage when cocking the barrel. I've removed it from the stock and taken a look - but, hmmm... am not sure where to begin. The safety does not seem to go all the way forward in its notch and I'm not sure if that's where I should start looking or not. I'm not too sure how to remove the trigger group - or even if I should at this point. "First, do no harm" is my motto. :-D Once I get an idea on how things work I can usually get 'em apart and back together again with little problem, it's the starting on a new mechanism that takes me a bit as I try to think it through before digging too deep. Any suggestions on where to start? Does anyone have one of these rifles? On a related note, if you DO have an original Model 303 Super, I'd like to see a pic of it. I've been trying to imagine what it was like before Rich started working it over for the grand kids.
