For sale is a large low pressure reservoir originally from a Temple organ. It’s in good shape. I think it has a small tear near one corner of the floating top. I can see it but cannot tell if it leaks as I’ve not tested it. Weights included as pictured but no springs. It’s worth at least this much for the flanges alone. Make an offer. Located near Gurnee IL, but can deliver within 200 miles round trip of Chicago for a fee of $1. Please contact me if interested!
