Subject: Please help: What kind of varnish do I have?
From: (Mike)

Can anyone provide any suggestions as to what brand/sheen of varnish
this could be (or might match)? None of the local boat stores seem to
know anything about any semi-gloss varnishes.

If the old owner was smart he use a good grade of interior one part poly.
They come in satin and semigloss, last longer, are easier to apply, less
expensive and water proof.
You can get them in small cans, so pick one up and see if that matches better.
