In your place I'd keep the stuff and watch for a porthole that has a crummy cabinet and complete chassis. Some buyers are scared off by things like peeling veneer or flowerpot damage.
That's my packrat advice for what it's worth. Portholes are actually more plentiful than you might think. Since the set has some family connection, it might be more fun to keep part of it, anyhow.
Just my $0.02.
