[Milsurplus] WLR-6 information desired

[elden meyer]

On the auction site is a pair of R-1450/WLR-6 receivers,
Item number 122004648594.

I have several tuning heads for these that I could not
identify until seeing the listing, as there are only part
numbers on the units but no equipment identification.

Does anyone have information on these, even just
voltages and pinouts?
Or does anyone need them enough to trade something?

I also have one of the Water Boy HF receivers, not quite
complete. Same questions.
