Update: with Photo ????Price Check 24 C with case????

Without a picture it's kinda hard to judge, as "fair/Good" condition really leaves a lot of wiggle room. However, I'd say the price is about right, Campers are pretty scarce and command a premium over regular 24's in my opinion, especially if they have the original case in good condition. Of course fair versus pristine condition does make a difference.

To give you an example of 2, I have a 24C Series S camper pictured below, in rather pristine condition with original case:

I bought that gun back longer than 12 years ago, prolly more like 15, and paid $300. If someone offered me $500 for it today, I'd laugh at them.

Daughter also has a 24C Series S Camper, not quite as pristine as mine, but pretty damn close, no case however. I would doubt very much  she would part with hers for $500 either.

Bottom line though is something is worth what someone is willing to pay for it depending on how bad someone wants it.

Would I pay $500 for it? Probably not because of what I already have, but if I didn't have one and wanted one, I probably would.

A picture would be of great help , especially of the case. If it's the tan vinyl case of the older campers and it's not cracked, that is a big plus towards the value, as most got brittle and cracked with age.

Good luck in whatever you decide.  

I think you did real good, I don't see how you'd ever lose money on it at that price even after holding on to it for only a couple of years.

I believe that case is some type of vinyl, and they are known to harden up and then crack with time. You might try talking to a place that does vinyl reupholstery /repairs and ask them what they recommend to condition vinyl and make it more supple.
