Are these j-valves worth anything?

[doghouse]

Not as collectors items or anything, but is it going to be worth the cost to have them checked out.

I received them a tip for cleaning a guys boat. He will not dive in cold water (60 deg.)

Thanks for any info.

Very little to go wrong with a valve. If they operate easily and don't leak they should be fine. No need to get them serviced unless there is a reason and just being old is not reason enough. I have 50 year old valves that have all original parts in them. The double manifold would be great for a pair of AL 50's. Or put them on ebay.

There is nothing wrong with those valves. Some vintage equipment divers really like those valves.
