Hi All; I have this meter for sale that fits into an R-390A hole. It is probably not from an R-390A but the movement shows "kick" with a vom. Appears to be "glow in the Dark" type Made by Bulova. Price is $24.00ppd. PICS: http://www.myradioroom.com/loadmeter1.jpg http://www.myradioroom.com/loadmeter2.jpg tnx & 73 Rich WA2RQY
