"Why doesn't manufacturer Y produce a kit of X instead of Y ?"
Now I know what I will ask for in the future:

I stumbled upon this image when Googling 'mzkt-7428'
It is included in some Hungarian forum discussion which,
https://sg.hu/forum/tema/1228481325?order=asc
judging by the images, seems to be about tank transporters.
My knowledge of the Hungarian language is totally nonexistent ...
