Hi Chris,

Depending on the exact leg diameters and center-to-center spacing it 
could be either a Rohn SSV or a SSV variant.  You will be able to verify 
one way or the other by measuring the leg diameters and center-to-center 
spacings as well as the orientation of the bolt holes in the flange 
plates.  Also, P/Ns are stamped on the legs and brace plates.  Here are 
the specs for Rohn's stock SSV sections:

Rohn made some SSV variants for Motorola's Business Communications 
Division.  I had the opportunity to buy one, but specifications are hard 
to come by, and Rohn does not give them out, for whatever reason.  Their 
parts are not inter-mixable with the SSV series, having flange plates 
turned at differing angles from the SSV.  The Motorola division which 
specified them is now gone, so that turned out to be a dead end for info 
as well.  In general they were used to support collinear arrays or 
verticals with little wind loading, and if you compare the size of the 
cross members and leg diameters with that of the SSV, you will see they 
are not rated for much loading.

If it is a stock SSV, you are in better shape as far as determining load 
capacity and getting parts.

Good luck and 73,
