Going by the flange propshaft mount an early 240z 5 speed, uses two piece propshaft?

Only kidding, can't recall to be honest, I was just going by the flange really.

Plenty of 'B' type 'boxes had flanged type outputs, as indeed does the one pictured.

There's no certain way of identifying it from a photo, except to say that it looks to be an FS5C71-B or FS5W71-B of the type that were fitted to many Nissan vehicles besides S30-series and S130-series Zs.

Short of opening it up and counting gear and counter-gear teeth, the simplest way of identifying it would be to trace it back to the car it was originally sourced from...

The other way is to attach a shifter and select the gears. My 5-speed is sprung between 3rd & 4th in neutral so If it doesn't go to the right and upward, you don't have a 5th gear!!

No need to even do that, as the F4W71-B is quite distinctive: It has a 6-bolt cover on the top of the rear extension, which the transmission in the OP's photo clearly doesn't.

It's a B-type 5-speed. Either an FS5C71-B or an FS5W71-B.
