A 833 or A 230?

picked up this transmission

http://flic.kr/p/94wPtA



it has an inland shifter on it,, have to pull up to find reverse, I believe that I can find 4 other forward gears
3 shift rods
a 1&2
a 3&4(od)
a reverse

but the stamped number on the case pad is
7G 103 400
PP 230 5514

A230's are 3 speed transmissions, with 2 shift rods
a 1&reverse
a 2&3

was there a A230 OD? ,,, the car this is said to be out of is a 77 Volare
so it should be a A833 OD.
any ideas on why the pad is stamped pp230 ?

thanks
