Thanks for the reply! The old one consists of plywood with the teak and holly veneer that is 5/16" thick. Other than a burnt orange adhesive that was as mean as you can get to remove, had no other fastener(s). No screws or anything. I found that to be somewhat odd considering how well built the Ericson line was. Perhaps this is not the original floor?
Best,
Frank
P.S. It was good to see your name after a long absence from this site.
