Can anyone tell us why RZM/1316/39 SS Carl Malsch-Spitzer, Steinbach and RZM/1221/39 SS Carl Malsch-Spitzer, Steinbach has two set of RZM numbers for the same year ?, And RZM/1317/40 SS J A Schmidt & Sohn, Solingen , RZM/1222/39 SS J A Schmidt & Sohn, Solingen changed RZM numbers from 39 to 40 ? It seems strange that they got two sets of numbers and when you compare the makers stamps and the styles, they are totally different and dont appear to be made by the same maker?
