I think there are only four HA-1112M1L available.
The fith is a Ha-1112M4L two seater c/n 40/2 exC.4K-112; ex7-92, ex471-56, exG-AWHC, red 11 in BoB filming.
Only two of these rare variant were built, one of them destroyed while in service in a ground collision in Nov.1963 so its a unique example.

The tail unit in this versión was taller; I am afraid she was fitted with one of a single seater
