On most art work / built kits of a z.b.v. 288 Sturmgeschütz there is only the tubular shaped air filters, but looking a new to me photo, athttp://www.bchomesellers.com/ww2/index
it looks suspiciosly like there is a rectangular box like structure over the air filters. Upon re-looking at the Bundes Archive Photo there is to me the same structure. Finally looking at the Life photo there is on the ground a rectangular box like structure. So the question is : Is it possible one or more z.b.v. 288 Sturmgeschütz had a structure over the air filters or No ? Or am I reading the photo's wrong.
I have uploaded larger photos in question to (1/2 way downish)
Am I reading it right or not?????
