This is in the Strong mansion at Sugarloaf Mountain, about halfway between Frederick, MD and DC. It is a privately owned "Scenic forested day park offering over 15 miles of hiking trails, picnic space & a historic mansion". I'm told Col. Strong built the mansion about 1916 and added onto it in the late 1920s. The mansion is also a popular wedding venue. See: http://www.sugarloafmd.com/
The facilities manager had sent some pics showing a standard Dunham air trap and return trap. I had expected the usual Dunham Return System- but that's not what I saw when I got there:
Triumph. Never seen this name on a Vapor system before. I could not find any markings on the traps since they had a lot of paint on them, but they look like a cross between a Bishop & Babcock and a Webster 712. There is one radiator inside a built-in cabinet that doesn't heat well, and it has one of these traps without the slathered-on paint. They're going to open the cabinet so we can replace the trap and take it apart. Of course we'll use a MEPCO.
The original part of the mansion has Triumph hardware and American Peerless column radiators. The 1920s part has American Corto large-tube rads and Dunham hardware. I have no idea who made the Triumph gear.
The boiler is an oil-fired Smith 19-9 with a Beckett CF1400. One of our upgrades will be to hook up the lo-hi-lo firing capability. There is a Skidmore boiler-feed pump which I'm sure is unnecessary.
