Type 1a - incised: This is the Mike Wald "Mark #1." There are at least five varieties of this logo and they were used interchangeably on steins manufactured in Freising from 1882-1886. This logo is found on both stoneware and porcelain steins. I know of no pieces marked with the "type 1a" logo that are also marked "Germany," or "Made in Germany." Note the large, "type 3" capacity mark.
Model 170 - This is an HR porcelain tapestry stein that is marked with the small "Gesetzlich geschutzt" and a "type 1a," incised HR logo, indicating it was made in Freising prior to 1887.
TYPE 1a STAMPS, incised - So far I've located five varieties of the "type 1a," incised HR logo. These were used interchangeably throughout the 1882-1886 production period. While there are minor differences they should be considered the same logo. Note the circled areas.
