I'm gonna have some fun w/your post, then I'll see if I can help you.
Picture this ... Put it on your front lawn, fill it with dirt, and let it be a flower planter!
Well, for sure, it's probably a little tooooo big to be used as a refrigerator door magnet. So much for the fun.
I've seen claw foot bathtubs selling for as little as $100 and as much as $8000 for a rare, side-plumbed tub. If you can find a salvage yard in your local, stop in and see what they're selling for. You may opt to just sell it if the price is right.
You can go to MasterPlumbers.Com, and read/search their Forum. There are a lot of people selling your type of tub as well as buying them. Other than that, I haven't much else to offer (unless you want a few more laughs. ;-) ) My best to ya and hope this helps.
