Bryant Pressure-Tender for Vapor Steam Systems
Thanks to Terry Tekushan for finding and sharing this one with us. He writes, "I thought this would be a nice addition to the museum. It goes well with Gerry Gill's submission of the Heat Tender. This one is a pressure tender for vapor systems. Both Gerry Gill and I have seen a few of these surviving quite well in the Cleveland area. I've not seen one on a Bryant steamer, but only on the B-Line which was apparently a subsidiary of Bryant. The B-line and Bryant No-Toi steam boilers from the 1920s and early '30s that I have fully serviced are the only boilers I've consistently measured efficiencies of 83 to 84+%. Remarkable. The ancients were clever."
