the finish was interesting. the trim I was to match turned out to be orange shellac coated in clear polyurethane. however the lac beetles are falling down on the job and orange shellac is apparently hard to come by.
as an alternative, I used two coats of amber shellac, (easily available,) well sanded. then a coat of reddish tinted polyurethane (prairie wheat) and a clear polyurethane final coat. note that the shellac can specifically suggests this is a bad idea, but the guy at Rockler insisted this was the norm… go figure.
