M-M switch panel

I have a dash mounted switch panel for a '65-'66 M-M ambulance. This may also be period correct for earlier or later years, but can't confirm that without digging out my factory brochures. Hinged on the bottom for servicing access once mounted in car. Will need to be stripped and refinished, and toggle switches and siren brake will need to be replaced. $50.00 plus shipping.

Same switch panel was used in the 1967 M-M ambulances as well.
