Can i have it ?

Look at the clutch mechanism. Its a hydraulic actuated arm protruding from the right side.

The only A series boxes with a hydraulic clutch were left drive models & they were on the left side.
The ribbed case would suggest to the unknowing that it's a 56A type 5 speed but the sideways projecting switches are a 60 or 63 series feature & the 56A had only one switch, ... for reverse lights.
This one has three. [Fourth gear detect, fifth gear detect & reverse]

It is definately NOT a Datsun A series gearbox.

if the rear of gearbox is long which it obviously is more than likely its outa a bluebird or sumthen with a l20 as most L16 &L18's that i've seen r short boxes

definately a 5 speed?
It has a ribbed bellhousing so wont be a 60 series. 56 series has ribs. look for a number on the side of the box

well it looks like a gear box.........looool
