Been spending a lot of time on here!
To my knowledge the only people who appraise film cameras are dealers who, like any dealer in used merchandise, will offer you an amount that will give them a profit when they sell them on. For example, you can send them to KEH and they will inspect them and make an offer. Or, you can bring them to one of the big NY camera shops like B&H. But, don't expect much.
