If you try to do anything in the 60s, have fun with those..... of 70/71/72. Thankfully I have good vintage dealers I see at shows and I can get some decent deals, but they still aren't cheap OR plentiful... I'm nearly done 73 myself, 22 short, and half are still the final series. Chasing NM or really clean ExMt (my Schmidt has great corner, o/c fully to one side though...) otherwise I'd be done already.
When the sky is coming down
When you feel like you're going to drown
When you know the end is all that you've been looking for
When the pain is too much to bear
When there's no one who will care
