O Day 12, Finding out if there are other owners

I have sailed and kept an O Day 12. I purchsed her in Key Largo and restored her. She today is in mint condition and has sailed all over Florida…My wife and I have had the boat since we were married, now going on 43 years. My questions is are there any other O Day 12 owners out there? Is there some way to network with them? Also would a boat like this be considered vintage? I know they have not been produced since the early 70s. Thanks in advance for any information.
