Nice little radio...tag on the chassis reads. Amateur Experimental Radio, under patents of RCA, so I am not sure if this was made by RCA......seems to get the same station on many dial areas......dial works good, but some static on reception.....Radio has  a very low hum, almost normal......wood is good all the way around.....cabinet measures 12" long X 8-1/4" tall X 7" deep......I hope someone can tell me more about this radio.....email me if you can,,,,,shipping in the U.S. will be .00
