Mine's a '68.
I just sanded my coamings down to bare wood in order to revarnish.
The original finish (what was left of it) gave the wood a dark honey colored appearance.
Sanded to bare wood, they have a yellowy/ light beige look. I'm guessing teak.
The floorboards are still original varnish, darker in color, and a chipped section shows a brownish/red grain throughout. I'm guessing that's mahogany.
It's pretty frustrating, as I'd like to add a bit more brightwork, but I'm not sure what wood to use.
There's a boatbuilder/cabinet maker not far from me. I'm going to bring him the pieces to ID, so I'll know for sure.
For the record, I've decided to go with Bristol Finish urethane for the varnish.

Pricey as hell, but has gotten some great recommendations.
