Thanks for posting this B. My alarm bells are going off... The MM is mimicking the early RZM 15 Hofstätter MM on the HJ honour badges up to around award serial 40000. My research shows me that there was only one manufacturer of the HJ honour badge in the beginning. This was Hofstätter who marked his badges with either FHB or, more commonly, RZM 15. Production was not meeting demand by 1936 and a contract was awarded to M1/78 Paulmann u. Krone who went on to produce around 55000 badges. M1/49 Baumeister is first observed on honour badges in the six-figure range and by then of course they had a correct MM with M1 - not "RZM 49". So, a Baumeister badge marked RZM 49 on a card dated 1942 is an impossible combination. Something fishy is going on with those badges.
