[Antennas] help with Wilson HF Beam

[Ronnie Hull]

gentleman
Last weekend, Marcel N5VU and I removed a large wilson HF Beam that had not been used in 25 years. We need help identifying this antenna. 
At first it looks like a System 36 style tri band beam but apparently had a 'ad on' kit of somekind put on it. It had elements that had traps on it but there was NO aluminum elements coming out the ends of the traps and instead of a six element beam it was a ten element.
I can provide a picture if anyone needs it.
I know it is a Wilson Antenna because I worked for the man that owned it in the 70's when he put it up and I remember telling me it was a SYS-36.

any help will be appreciated. Thanks
