Allen, not really.
Fact is and as stated by a german member, the abbreaviations are indeed not correct and the handwriting is not what we learn when writing german (I had to learn the opposite when I lived a few years in the US. Nobody understood my 1 for a 1 as its rather written as a I.) It might was someone being fluent in both languages or someone from the US working now in Stuttgart. The note is also larger than most german writings on kardex, which btw, write 1 for a 1.

It does not change anything to the fact the "deluxe" models existed, as you have made proof in this thread.
Just agreeing with the member from Germany and recalling on something I always spotted.
Wonder who wrote it as its clearly added afterwards, in style unusual and also as an abreviation.
