[Milsurplus] aircraft antenna

[Mike Hanz]

Excellent find, Tom!  The insulator segment is clearly visible at the 
top.  It's a shame there is no hint of a nomenclature, especially with 
the 1945 MFP label.

If the Euro goes down any more it might not be such a bad buy for someone...

I still think Dyson stole the size and shape... :-)
