hello can any one tell from these numbers what this gearbox is 22G 1555,OTHER MARKS 3 TRIANGLE THEN. E,, i think it is probably spitfire but not sure thanks tony

i think its a1500 MIDGET BOX. ????????,, GRANDAD

The photo on P.146 of Haynes Midget Workshop Manual shows a Midget 1500 gearbox with the markings 22G15?.
If the box has overdrive it's a Spitfire box. If not it's a Midget box.
