Jun-- I, too, was unable to locate the valve from a PetsMart. I did, however, find a metal double valve by Penn-Plax; the name on the bubble-pack card is "Penn-Plax, Lok-Tite, Brass aquarium gang valve" which I purchased for $5.99 at a large, no-name pet store. The address of Penn-Plax on the card is 720 Stewart Avenue, Garden City, NY 11530 U.S.A. There is no telephone number. The problem is that you may want to fabricate a holder for the gang valve, which snaps out of the plastic holder that is designed to be hung from over a ledge. The catalogue number on the card is V-2 1/2. In working on the BAGRS project loco, I have also found that the Acme fuel tanks are no longer manufactured in brass--everything now is fiberglass or plastic or some such material. I found a dingy hobby shop with very old stock, and the owner dug out a few old Acme brass tanks. I ended up buying a "U-6" and cutting it down to size and then reattaching the end from the piece that I cut off. The "U-1" proved too small. I even had a large shop that specializes in model aircraft try to order for me the one specified in the SitG article, and the shop was unable to locate one even from other shops. If someone has a better fix on the fuel tank, please post to the list because the modified "U-6" is less than satisfactory. Bob Blackson
