I hoped that someone might recognise the serial number format "M6A00214", maybe someone will.
the serial number IS going to be the best clue, and our resident serial number sleuth (T-Mar) has been inactive, lately. If he sees this he might have some insight, but most of his expertise is with the big factories where this could be from a "boutique" low-output builder. Clearly it's a fine frame, even if it never gets a name.
