Well, historic info on the Proof Facility @ Mellrichstadt is elusive and Heym Tube Maker Ford(in the Tin Lean-To) is about the only source. But München and it's Satellite Stamping Station Mellrichstadt also serves as Bavaria's Weights & Measures Office and has the Status of a Proof Facility.
The Sauer influenced Eckernförde Proof Facility was founded in 1952. In 1953 the Hannover Proof Facility was up & running in a limited status till April 21st, 1955, when it was granted the status to proof everything. It had the mark of the Rampant Colt. Roughly it is 300 km between Eckernförde & Hannover. Eckernförde looks to be in a cold & miserable location. Not sure when, of if, Eckernförde was shuttered?
