After collecting as many serials I could find (still collecting ), I managed to derivate a list of serials and matching references and also a assumption of production numbers in the end.
Since there is are a lot of definitions of MKI , MKIc or MK IV out there, I tried to tie these classifications on serial charges and building dates.
