Worth more to restore than potentially trash it by "steampunking" it, that's for sure, especially if it is an heirloom. Far too many nice antiques have their historical value destroyed by being turned inot dubious art. Yes, I'll admit it, I'm a curmudgeon on this...

Advice from a collector? Get this one properly done up. If you want to steampunk something, find something modern or less valuable to have a go at.
