Not fully Ken61.
A premise surrounding the the term Saxony paired w/ the Crossed Sidearms surmounted by a Crown was a stop gap measure to comply w/ the 1890 McKinley Tariff Act which was effective March 1891. More than likely the British led the charge on this requiring the Germans to stamp their wares to indicate the country of origin. Preußische Sachsen would actually be the term but the Brits required the name in the origin stamp to be either English or French, and the Americans more than likely followed suit. Japan had the same identity issue w/ Nippon & English term Japan. Then say in 1893 the Germans could no longer use the term Saxony as the name in the origin could not be a city, province, state, department or other division but rather the actual country of origin. So when H.A. Lindner made the transition from his QA/QC stamp of Crossed Pistols surmounted by a Crown to Crossed Pistols surmounted by HAL, the term PRUSSIA was added to the lot to replaced the inaccurate/invalid Saxony state term. It would be a viable option to date German wares with the origin stamp of Saxony between March of 1891 and say March of 1893. So when Suhl actually learned their identity w/ respect to exported wares, then Prussia was used. Remember on the average the time from which a sporting arm was issued a serial number to the final state of completion could have been as much as 6 month(per Daly).
