[TenTec] #311 band data converter

[JACrux]

I have an unused #311 and the interface cable to connect it to a 565 Orion. 
I got it to interface an Orion to a Hercules II (420) and/or to the 253 
auto-ATU, but as I never got the Orion, I have never even unwrapped it.
No other info --- at all.
Does anyone need it,   and if you do,  what is it worth ?  
I can mail in UK, or from Florida at end November.
