  Externally similar to Airline GEN-1212 Collie.

  There seems to be several versions of the circuit. An earlier version used larger HJ germanium transistors from Hitachi (OV-5 can) which look similar to early GE germanium transistors like the GE 2N107 without the tip on top.  Later versions used round tin can type transistors typically found in Japanese transistor radios in the 1950s and 1960s.
