Gearbox serial no questions
 

I have a Sportomatic gearbox that has 905 / 21 stamped on it with serial no 23954128 can anyone tell me what year and model this could be from please and confirm it is a 3 speed

I also have a 902/1 gearbox with a serial no 235805 am I correct in thinking this from a 1965 - 1967 911 or 912 and is a five speed.

Thanks in advance
