Help Identifying WW2 radio

[Joe Connor]

Someone asked me to help identify a WW2 radio that he has and I'm stumped. I've attached two pictures. I'm sorry about the quality but they're his pictures, not mine. (Mine would probably be worse). The owner believes it's from a fighter plane but it looks way too big for that.

Thanks for your help.

I think I know but real photos would help, not thumbnail size Joe.

50x50 pixels just isn't viewable.

Let's see if these are better.

I apologize for the earlier ones. I thought that if you clicked on them, you would get a full-size image.

Looks homebrew to me, if it was a military radio, it should have (or have evidence of having) a data plate somewhere, usually on the front panel.

Yup, looks like it to me as well.

"Never seen it", Been down the "Smellow brick road"

It's a Hallicrafters ARR-5, re-packaged in a HB cabinet with power supply.  Very well done though.

The ARR-5 was +/- the airborne version of the S-27, with motorized tuning and an external 400 hz or dynamotor power supply.  It was most widely used as an ECM receiver in RB-50s and RB-36s in the late 40s/early 50s.  Probably not WWII although as I recall some were used during WWII for radar ECM.

Here's a pic of an ARR-5 with the cover off, note the identical chassis in the subject radio.

Thank you, John.

Boy, do I feel stupid. I actually have an ARR-5 in its original case. I knew the front layout looked familiar but I couldn't place it.

I assume those chokes and transformers inside the home-brew cabinet are part of a home-brew power supply. Perhaps, there's also an audio-output transformer to drive a speaker. There seems to be an awful lot of components hanging loose in that power-supply compartment.

Actually, that top, loose transformer looks like a doorbell or 24 v furnace transformer. It looks like it was just stacked in there by someone. Probably just loose parts.

I had the ARR5 in my head when first posting but that blur for photos and that front panel didnt help!

Glad it is resolved.

John, my Brian is now at the embassy in Tblisi for an 18 month stint. Any good surplus shops out in those boonies?
