The last two that sold on ebay went for $52 and $75. Condition seems similiar to yours. I'm sure there are many of us on these boards that would like to have it if you decide to sell.
It's definitely on my wish list - as in hope to run into one in the wild one day. The only reason I didn't include it on my Oddfellows thread (linked here), is because it uses a conventional worm-gear. The innovation is the hinged handle.
