On May 19th, 1892, Germany saw the Reichstag pass the new German Proof law, which was made public on June 22nd, 1892. It became effective on April 1st, 1893.

I still recall some new information about the >>Vorrat<< stamp begin applied for a period of a month only? In retrospect, a month or a period from January 1st to April 1st, 1893 is splitting hairs and pretty much semantics...

Looks like the crossover in Lindner's stamps hovers around Nr. 450 in the 2nd series.
