[Milsurplus] I-208 signal generator value

[George Babits]

As I understand it, the I-208 Signal Generator is specific to the SCR-508 
and SCR-608 FM sets (19 to 39 MCs).   Wondering if they are scarce, rare, or 
rip and strip category.  I have a beat up one I'd like to make go away but 
need to get some idea of its value.  Certainly a genuine boat anchor with a 
shipping weight of about 110 pounds!

Thanks,
George
