As you said, very nice gift!
Here...
There are plenty of obscure parts, even stuff the real afficionadoes consider obscure. I doubt many us in C&V would call the parts on an early eighties Daccordi "obscure"
Hard to tell you about co-ops, etc, if the only thing we know is that you used to live in NY...
Welcome to BF, and specifically to the C&V forum!
Cheers, Eric
