I have four, 4 cavity ingot molds for sale. Made from some old “U” shape steel posts and angle iron. These make an ingot about 1 lb and fit beautifully in a SFRB. It’s been awhile since I shipped a SFRB but if I recall correctly you can get 22 or so pounds in. I tried dusting one with Smokes powder and baking it but more trouble than it’s worth. If someone wants a mold PC’d, I may get a Harbor Freight Gun and try that route.
I’m listing these at $25 each, plus shipping in Flat Rate Boxes.
