I have an ‘85 Mac 25, which came with particle board bulkheads plus all the “wood” hatch covers in the cabin and all are covered with wood grain vinyl. If I had more time, I would replace the particle board with some sort of real wood and finish it nicely. A project for another time...
The table is real wood. Trying to find my notes from years ago when I inquired about that. My tired brain is thinking MacGregor had said table was made of Brazilian Teak.
Hope this helps, and good luck! Send pictures when you’re done - we like pictures here on the forum!! (Might even motivate me when I see your finished product...)
