You are going quite well with your little family, MKI, MKII & MKIIIB so far.
I'll try and dig up the cowl with the notches, to give you with this MKIIIA base i have for you, that way you will have all 3 cowls in tyour family.
I have now worked our the full variants range, I beleive:
1970-71
MKI (Base 1, Cowl 1)
1971-72
MKIIA (Base 1, Cowl 2)
MKIIB (Base 1, Cowl 3)
1972-73
MKIIIA1 (Base 3, Cowl 2)
MKIIIA2 (Base 3, Cowl 3)
MKIIIB1 (Base 4, Cowl 2)
MKIIIB2 (Base 4, Cowl 3)
Wlile the MKI, MKII, & MKIII Variants represent different year models, I beleve the other variations are specific to some being cast on different presses, but not at different times
I wouldn't bother trying to get all of them, What you will have soon, is the 4 main variations, MKI, MKII, and the 2 different MKIII bases (One being the normal MKIII base, the other being cast in the same machine as the Auto Drive)
