[TowerTalk] Help in Identification of a Crank-up Tower

[Steve Marr]

Can anyone help me identify the model of a tower and it's structural
specification from an old factory spec sheet?

Tristao Towers 115 E Fifth Street in ?, CA, (the stick on label is so worn
it can not me read).
3 section crank-up each section approx. 22 feet in length.
Lower section 16.5 inch triangle to the center of the legs.
Lower section legs are 1.25 inch O.D. with 1/8 inch wall thickness
galvanized.
The top 2 sections are 1.0 inch legs.
Flat thrust bearing plate factory welded across the legs at the top of the
top section.
All sections have a 1.5 inch D type light gauge steel wire ring welded to
them at the top of the section.
Tilt over base.
Z braces welded at each junction with small C channel braces welded at the
top of each section.

Any help or copy of a spec sheet is appreciated!
