Hello, all.

Here are the numbers

chassis 116028 12 048850
engine 116985 12 013858
control pressure regulator BOSCH 0438140 056

More of that: near the table with chassis numbers to the left there is one more plate with many stamped numbers. It looks like this:

04D 8546726 43
116028 12 03182 2
876G M -
260 420 466 511 580

I don't know what does these numbers mean, especially second string.
