    This set was first advertised in various November 1922 advertisements as the Michigan Senior. The set was identical to the Paramount 3-tube receiver manufactured for Paramount by Klitzen which would suggest the Senior was also manufactured for Michigan Radio by Klitzen using Klitzen's Armstrong Regeneration patent. Starting in January 1923 the receiver was also referred to as the MRC-7 Senior.
