Dutch lacquer cutting engineer at Bovema / EMI Studios, active between 1961 and 1968.

Lacquers cut by him between 1961 and 1968 can be recognized by an etched "HM", e.g. HM001385-1, where the first "H" stands for "Holland" and is not part of the ANV.

Lacquer Cut By - M (58)

Please note: starting 1971, the etched "HM" was used by Henk Horden. So, please credit releases since 1971 to M (111) (Alias of Horden).
Do not confuse with Dutch Imperial releases with matrix "7 HM ####". Only credit to M (58), when there also is the HM##### stamp.
