Al,
You also need to look for these markings before you can decipher the colours.

Ignore the red circles, you are looking for the yellow markings on the crank webs.

Thanks

Not very clear but under a torch they are all 1

And to be honest would not even know they there till you pointed this out

(Building a 2T is much easier)

Your con rod weight codes look like you have three weight codes 1.3 & 2 not sure if thats original ? Ah no the weight codes are letters probably on the other side.
You need to look hard at your shells to find any remaining colour codes if you can. The crankcase codes just give you one axis on the charts. There will also be codes on the crank for the big end sizes. Quite hard to find in my case.

If you can't find any colour codes then you will need to measure the crank journal sizes and check them against the parts code charts & then Plastigauge to check the clearances if necessary using a known shell colour as a starting point..
