DAF Sch(ule) marking? Need help!

[pimpf]

Hello! I have got a fork with DAF marking on it but there is an abbreviation under the DAF emblem:

MDA Sch.d.A

Any ideas for what this stands for? I guess that Sch. is for schule (maybe Schule der Arbriter)? Any help will be appreciated!

Hi
nothing to do with a "Schule" :
Modell des Amtes Schönheit der Arbeit.
