i have a small pile of book from may different publishers ..about the brmmbar ...
in a nut shell .. there were 3 models early . mid and late ..... but i have a pic or two of and early brummbar ... with the early gun .and panzer 4 type drivers visor
but fitted with a mid production roof ! .....now i know its a mid production roof becaues there is a forward set of roof doors missing and a slide type periscope mount and a roof vent ...
can any one say .. if between model changes .. the bits thay had left over thay fitted any way

i hope there is a real track hear out there that nay be able to shed some light ??
