[R-390] Green Panel R-390A

[W4QG]

Hi Everyone,

I picked up an odd 390A at Shelby last weekend.
The front panel, knobs and meter covers are green.

Looking around the net at the usual places I found no reference at all 
to this variant.
It certainly appears to be original.

Silk screened panel, the knobs appear to have baked on paint. Signal 
Corps tag on it.
I have not pulled modules yet. Looks like it has a tuning reduction gear 
on it for fine tuning.

Could just be a wacky modified radio.

Any thoughts? I can shoot pictures for those interested.

Thanks and 73,
Paul W4QG
