Billings Boat
HI John
This is very reminiscent of "The Fisherman" model by JL Rowell, and subsequently offered by AA Hales under their "Yeoman" range. Vic Smeed had a similar offering "Moonglow" around the same era. if it is a Billings offering then its possible that the cabin uses their (very) brittle mahogany type wood (my Billings Mercantic did). I don't expect it to have weathered well over the years and any glue joints, even with cascamite, will probably be separating, just alongside the glue joint.
I am not criticising, the kits are some 50 years old, and at the time were very popular and made into very realistic models. 👍
I hope someone can make a positive identification, and look forward to hearing how you progress with the restoration. 😀
Live long and prosper
