Looks a lot like Colonel, but the stencil gaps aren't quite as wide.

Seems to be the stencil version of DIN, 'DIN Schablonierschrift', by Marian Steinbach..

Edit.: Well, too fast, I am sorry, 'DIN Schablonenschrift' doesnt seem to match, either.. Hmm..

Thanks for theses answers, it helped to resolve the problem.

Probably too late but that one is Housebroken.
