Thanks Joe,

It is obviously a 3A7428. I used you link and there is a site member with 3A7427 but unfortunately has posted no photos. 1973 makes sense based on the looks. Quick question, did the bottom of the 1970s models start to get a bit more dead rise than the 1960s 16/17 footers?

It is "custom" for sure, no interior, road rash on gunnels. Good news is no bottom paint.It will be quite a project but I may buy it anyway.
