Kind Hooptyreader Jim pointed out that I don't have a Gumco, I have a Gomco. Jim couldn't be more right. If you search for Gomco and go to your local Suction Unit and Aspirators Shop, you can buy a machine remarkably similar to mine for a paltry $2350. Of course, mine is an artful piece of medical history from a time when great design and manufacture were the rule, but at least you won't have to do without. Or, I will trade mine for custom bodied pre-war fine American and European automobiles.
