Calectro DC Microamperes, No. DI-912. Box label reads: Precision Meter Accuracy 2% of Full Scale. Jewelled bearings: D'Arsonal Movement. 0-1 DC Milliamps.
In very good condition. Face is 2 3/4 x 2 1/4 inches.
I have no way of testing these meters so I can not guarantee that they will operate as they are designed to operate.
