I have recently completed finishing my unfinished attic (almost). The
attic had plaster walls and a wood floor installed, which seemed to me
that they builder had intentions of finishing it. The house was built
in 1850. There are also two pipes for a radiator run into the attic
(cut through a shaped plank for that radiator to sit on). I want to
start looking for a salvaged radiator but I want to make sure that I
get the correct size. The pipes are about 43" apart. Most of the
radiators that I see online are measured in height, not width. Any
help in selecting a radiator would be greatl appreciated.

Thanks,
Tom
