FS: GR GENRAD 510 decade resistance units New old stock

[volvo_nut_v70]

Six GR 510 decade resistance units. These units are new and unused in their original boxes with the original plastic protective bag, instructions, can and knob. (one unit does have an original used knob). I bought these new in 1979 and never ended up using them.

GR 510-B 1 ohm steps
GR 510-C 10 ohm steps
GR 510-D 100 ohm steps
GR 510-E 1000 ohm steps
GR 510-F 10K ohm steps
GR 510-G 100K ohm steps
I would like to sell them as a set. I will include an used 1K unit that does have one burned element.
