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.

No Idea yet, since there a so less around there. My guts tells me not more than 500 in total, maybe less.
