I will compile a short list here ...

Note : I've used references from Wikipedia, Subaru + others on here to compile the list.
For ID purposes, there is usually a sticker or part number stamped on the box ...

I've broken them down into the following categories :
Generally - I've shown the 'index' code for each type of box & what it went into from factory.
( There are too many variants to show 'em all )
Feel free to suggest any that I've missed or corrections to be made ...

Notes : This is a work in progress - Aim is it to include it in the Wiki page ...
