Ah, yes! I now recall that I used to know this. Maybe what he had was a
Spaulding version? But it definitely had the swaged, stepped-in taper,
instead of a continuous taper like Delhi. Maybe it was a Spaulding? A
little bot of Google-fu turned up that when Rohn bought Spaulding, they
changed the design quite a bit and used heavier gauge steel. From what I
read, the Spaulding and Rohn BX series are similar in name only -- no
parts are interchangeable. Still, the Rohn documentation says no booms
longer than 10'. I have to wonder of that's simply a holdover form the
Spaulding rating or of Rohn re-engineered all the ratings?

Maybe... He said it was an HDBX48, though. Have these things bee
cranked out by different companies since the beginning? I always
assumed that in the beginning, they were exclusively Rohn. Of course,
I dunno when the ???beginning??? was, so maybe by 1968 they were made by
everybody...

Before Rohn, they were made by Spaulding.
