Is it a bottom pour like that shown on the label and what is the lb capacity? I had one (received free), the only objection was that it was only a 10 lb capacity. Otherwise a very good furnace. So if the capacity is only 10 lbs, I would value it at no more than $150. Should it be 20 lbs or so, give it at least twice that.
It is a bottom pour. It is 11 lbs.
How does one make it pour? Or more specifically how do you stop it from pouring till you're ready? It has a hole with a nipple on the bottom with no stopper.
Look at the curved handle on the right on the label. You raise that to pour and lower it to turn off the pouring. You adjust the height that the handle raises to control the amount of lead coming through.
