Thanks everyone, and special thanks to Lee for the cool (as always) photos and Dave's opinion, although, I'm disappointed I didn't get a Dave Pun - something like being flabberglassted or "not being clearly divided on the scoop" or "green gel coat envy" or something similar!
In any event, it's not worth it (to me) to investigate further as the current owner is looking for low four figures for it! And "it can sit another thirty years as long as he cares..." side note, it'll no longer be his issue by 2050...
