Sachs 125A case Identification

[454MRW]

I went to Dave Sanders shop yesterday and among other things, Dave showed me these Sachs 125A engine cases with what appeared to be hand stamped lettering/numbering. Has anyone seen this before, or know who might have been the individual who stamped them or the reason? He wrote the stamping in black marker to make it easier to read. Mike
