I'm not sure about the Kodak camera, but maybe a collector might be interested.

The Pentax gear is definitely worth putting up for sale. You could probably sell all of it pretty easily on Pentaxforums.com. However, to sell it on PF's marketplace, you'll have to become a paying member for a nominal fee. Otherwise, you could just send the entire collection to Keh Camera for a quote. That latter option won't get you top dollar, but it has the advantage of one quick sale.

I have a Pentax ME Super and collection of Vivitar lenses I keep as memento's.
The Me Super and the Spotmatic have a general used value of $50.
The Colorburst is shown on Ebay running from $15 to $25 for a "buy it now" price.

We'll then, these are for sale if any one wants them. Part of an inheritance that no one wants. Seems shame to toss them

I started shooting mostly film a couple years ago. I enjoy the process. I like waiting 3-12 months to finish a roll, and then sitting on the couch with family and going through the prints the first time. Might be something to try, if you haven't tossed it.

Otherwise National Camera in the cities would probably buy it.
