[Boatanchors] digital dial readout

[LARRY D GODEK]

Almost All Digital model DFD103 digital frequency display.  Was this made for Collins gear.  Seems like i recall seeing eithe this or one close to it years ago that was an enhancement and gave better resolution than the analog dials.  Has a BNC connector on the back for input along with power input and a button to push for Cal.  Front controls are Band, Mode and of course the digital display.  
 
Like to know what it was for so i can offer it for sale on one of the lists before going to an auction site.
