With apologies up front, Ray, maybe it is time you did joined a club.
Age brings limitations, but with your life time experience with Model A's, it's kinda selfish to keep all that talent to yourself. Meet some of the guys for coffee once a week and talk about your mutual passion. (You & the Model A need the exercise.)Maybe there is someone in the group that needs a Model A

Mentor.......and might be half your age to assist with those pesky Model A get out & under projects.
This age thing sucks, doing it alone, worse.
