Interesting, Bruce, thanks for that. When I get this item home I will post photos of it.
The “105” prefix number block shows up in the 52-Set Parts Lists from CMC for the meters used in the set.
Now my curiosity is peaked regarding why the 29-Set was issued with both a variometer and an aerial matching unit. Technically, they both do the same job, but perhaps a variometer has better efficiency with tuning whip aerials and the CMC Matching Unit was better working with long line horizontal aerials in a Base Station environment.
Do the mysteries ever stop, Bruce???
