Well, before the repost I was trying to get an idea of how you're marketing it currently in the app.

A plumber company may take it or a pawn shop.

If they have an offerup account you can even be rated.

At the price point and size some of these start off at, I'm honest not sure how fast it would sell.

All you can really do is reasonable price it based on online shop rates, have good images and description if you plan to sell on OfferUp

Did it come with a house you bought?
