I understand, but I guess it would depend on what you want to do with them. If redone, they're likely to go into his auto restoration shop so they're not being flipped and they don't have to look perfect, though they wouldn't be abused or get too filthy ... that shop is like an operating room.
I sanded the top of one of the speakers and it cleans up pretty well. I think the veneer can be made presentable, though obviously not perfect. Grill cloth is cheap, so I think they can look pretty good, at least from a short distance.
I look at it as a project, just like the old cars we work on. If a person drops $300 for parts and gets a pleasing (in a sound sense) pair of speakers, then why not? Heck $300 -$400 doesn't get you a lot around here, there's not much to choose from at any price.
I've brought worse back to life ... somewhere around here is my thread on a literal garbage dumpster AR 93Q pair, and they sound great, though still ugly without the sock.
