Hi Donny,
That's one of the first model 45's to be made as the engine is an early 1968 issue. Can't quite read the code that you've put up as it goes out of focus.
It's in fabulous condition and really hasn't done that much work. Give it a good clean and relube and you'll find after a reel and bed knife grind it will be as good as a new one. It's in much the same condition as my original 45 that I started with and I used it like that for over 30 years until someone stuffed the barrel of the block when re-ringing it which was it's only downfall as it was puffing smoke like "Puffing Billy".
Cheers,
BB.
