Ed,
I met Randy at one of the N Scale National Conventions. A very nice guy. Here is a link to his "non-Ebay" web site: http://trainsbyrandybrown.com/
Also, I believe he acquired the old Arrowhead Scale Models line. I have the Arrowhead #60-103 kit (among others) that looks like Randy's N-103 Downtown Fire Station.
Not an acquired firm, Randy formerly manufactured products (i.e., circa 1990s) under the trade name Arrowhead Scale Models.
With some of the items offered in ready-to-use, factory decorated form, the resin products marketed under the Arrowhead Scale Models brand were composed of quality, flash-free castings.
