> I recently asked a question about HDBX 48 torque loading. Another
towertalkian told me his failed in about 80 MPH winds. He sent me a picture of
his failed HDBX 48 (more heavily loaded than mine by a fair bit) that failed.
Something I noticed in the picture was that his HDBX48?? had only *five*
X-braces per section; I thought it looked odd, so I went out and looked at
mine: mine has *six* X-braces per section. He said his was manufactured
sometime around 1968-1970 while mine was put up around 1986, so was probably
made around that time.

Nope, your eyesight is ok. The original tower you saw was the AX.
