I have two S-meters for sale that go in R-388 and 51-J-series Collins
receivers. One is a Burlington, seen in most R-388's and one Honeywell
seen in later 51-J-series receivers. The Honeywell has a slightly
convex glass design, the Burlington is the conventional flat face. Dial
scales and movements are identical. Condition: Exc.

Either on $45 plus postage/shipping/insurance of your designation.
