[Milsurplus] Looking for a radiosonde.

I know some of us collect radiosondes, and various bits and pieces.

I'm looking for a somewhat common older military model, the ML-659(V)2, 
whole, or in part.

There was a V1 and a V2, the difference being what type of VLF 
navigation receiver was inside.

There is a listing on ebay, to see an example of what these look like, 
if one isn't familiar with the model:

What I am looking for, specifically, is the 403 MHz transmitting 
antenna.  The model on eBay has a little single wire whip antenna, which 
can be seen further down the page.  This is NOT the type I'm looking for.

What I'm trying to find, is the antenna with crossed elements, known as 
a Lindenblad Antenna.

The different antennas don't seem to track with the V number of the 
sonde, so unless one eyeballs the antenna, the sonde could have either 
one inside.

I've can directly send a picture of the type of antenna I'm looking for, 
along with the antenna I'm NOT looking for.  The images are labeled, 
with arrows.

If anyone has complete sonde with the crossed element antenna they'd 
like to sell for a reasonable price, I'm interested.  Or, if one has 
some of these funny little antennas that aren't bent up, or mangled, I'm 
interested in just that one part, actually, not the entire sonde.

Let me know what you have, if anything, or, maybe some sources.

Kurt
