What is this number stamped on belt?
R.B.Nr.0/836/0111
What does it mean ? And when was it used ?

[wilhelm Saris]

R.B. means Reichsbetriebsnummer (the number for a specific company). I have a list, but as there are thousands of numbers I do not know if I can find the number you mention. By the numbers it is possible to find out who this is, but the official list has many gaps and it is possible the number mentioned is not included.
