[TowerTalk] Need info & manual on 20 meter beam

[Chuck Frame]

I have a 5 element 20 meter beam on a 46 foot boom.
The boom is 4" od tapering to 2.5' od at the ends.
The elements are 1.5" diameter. This beam was made by Hy-gain. The 1967 catalog I have calls this (DX Long John 205B) Rated for 125 mile wind and built to "Commerical/Industrial Specifications"
Wind load: 18.1 sq  Weight185 pounds.
I need the manual so I can put it togther. Anyone had one of these beams I would like your input
