I think you will always have some similarities as, on the whole many are made in the same factories as there is not from what I have been told, a K&C factory and a TG factory etc but, for me, I think they hit the ground running and, captured a realism that takes other comapanies years to crack even, some of the big ones today find it hard.
IMO from day one with the MG34 they were what the hobby needed
