Nice find Martin. These unusual outside B's are found as early as 1940 and then are used sporadically throughout the remaining years up to 1943 as I have determined to date. I assume it was another inspector with a different die or location, one. In the later part of the thirties we found a number of different sized eagle B's being used as the police authorities apparently weren't concerned with exact copies of the original die but only similarities, of course in my opinion.
