Looks like sections from a Rohn BX or perhaps even HBX...but like others have stated, it's hard to determine from the picture.
BTW, I have a 48ft Rohn BX (shortened at the top to 44ft) with a Hygain EXP 14 on top of it....handles it just fine..
It may handle it fine, but it could be impossible to get a permit for one with an engineering inspection, since the Rohn BX engineering documents clearly state that the tower is not rated for antennas having boom or element lengths longer than ten feet. If you need a permit and an engineering review, this wouldn't fly for most HF beams.
If you don't need one, it might work for a long time!
