Great article Marcus.
I don't have a part number on my original or my repro bag which is the case with those you pictured too.
I presume the instruction card part number never changed up from A to B like the aimers?
I didn't know about the A and B aimer versions so I checked what I have, and it's one of each.
I scrounged them loose (no sign of any bags) at the wreckers years ago and never looked close enough to realize I picked up mismatches.
I need the A version for my early car, but don't have a proper set of either version.
Could be worse though, imagine if the bags and cards had changed too.
I did notice that the service manual illustration is of a different version of the tool in your pictures.
Here's a couple of pics of the tool that is an exact match.
