I need help finding a f couple bolt-together baseboard radiator sections.

The sections bolt together with compression fittings between. I think it was
installed in this midwestern US home sometime in the 1970's. Holes are 1"
diameter and 6.5" on center. Section is 9" high and 2" thick. Need
approximately 3 1/2 feet total (two sections). One section must be a
right-hand end piece. Also need some associated sheet metal stampings for
end and corner. Any info re manufacturer or possible sources would be
appreciated.

I have posted an ebay "Want it now" that includes a small photo.

Any ideas where I might find these sections would be greatly appreciated.
