Danish to English Social Sciences History

In a 1901 census record from Odense, Denmark, an individual's occupation is recorded as "kommunal trommeslager." Ten years later, the same man is called simply "trommeslager" and his employer is recorded as "magistratet." In all the Danish dictionaries I've checked, "trommeslager" is literally "drummer" but can also mean "town crier." Would the use of the word "kommunal" before the word suggest the latter as the best choice here? The individual involved was originally a "patrouillebetjent" (patrolman) in Odense as a younger man, later became the "kommunal trommeslager" as a middle-aged man, and finally as an old man is listed as "desinfektør" employed by the "sundhedskommission." I know of no musical talent, so doubt the literal translation of "drummer." Any suggestions?
