I'd say, keep it, read it BUT keep it pretty nice, as it looks...someday, someday...you may part with it and should do so at a maximum.

I used to be interested in restoring vintage small appliances, specially Hobart and Sunbeam Mixers and managed to score a repair manual for all Sunbeam small appliances...this was the one certifid repair guys got with schematics ect...

Anyhow, nailed it at a local auction for about 6 bucks, read it, used it for about 3 years and then sold it for about 250.....that 250 funded my first Fly fishing purchases!

Don't always go the eBay route, offer up to "known interested" groups and ask for a fair price...you'll get it!
