The Harlow PJC-5 is a derivative design from the PJC-2.  After building the PJC-2, the Harlow company designed and built a 2-place military trainer.  The PJC-5 is essentially the same airplane but with tandem seating and a bubble-style canopy, ala T-34 :: Beech Bonanza.

The PJC-5 was never sold to the military in the US, but a deal was made with India.  PJC-5 subassemblies were built up at Alhambra and then shipped to India for final assembly.  PJC-5s are apparently fairly well known in India although long gone from flying status.
