Yeah, just google for "1/72 ship fittings" or some variation on that. I'm sure somebody makes some stuff. A lot of captains will just make their own stuff from scratch though.
Didn't notice your post until just today. If you are still interested in 1/72 and need outfitting items, I may be able to help. We have a large 1/72 club here in Northern California and the Reno Nevada area.
