Model 4 - This is an Freising model number 4, but it is marked with the logo of "A. Wahnschaffe." The entire logo reads: "A. Wahnschaffe königl.(ich) bayer.(ischer) Hofieferant Nürnberg." This tells us that A. Wahnschaffe was located in Nürnberg and that he was "Purveyer to the Royal Bavarian Court." This is the fourth company the Freising factory apparently produced for in addition to their own production. These are the only two pieces reported to date.
Model NMN - This cat appears to be part of a set. While it has no model number, it could go with the 3.0 liter cat, HR number 305.
