Collins Radio 51S-1

                                                       COLLINS  RADIO 51S-1 HF Receiver


Large Round Emblem 1972  S/N 8435 ANAMOSA MADE

There were two types of meters  used it the 51S-1, one is made by Bartlett, and the other one, is made by Honeywell. 

The Bartlett does not have any brand printed on it but the Honeywell has the Honeywell name stamped in the lower left side

There were a few early 51S-1s with a Simpson Meter face but very few had this meter which is slightly different than the two mentioned . 
Mine is the Bartlett's prod.

This is not an S-meter, this is RF input level meter, but this is good for communications receivers.
