Just to recap, the McKinley Tariff became effective on Oktober 1st, 1890 and the Country of Origin on foreign goods imported into the U.S. of A. per the following:

"That on and after the first day of March, eighteen hundred and ninety-one, all articles of foreign manufacture, such as are usually or ordinarily marked, stamped, branded or labelled, and all packages containing such or other imported articles, shall, respectively, be plainly marked, stamped, branded, or labeled in legible English words, so as to indicate the country of their origin; and unless so marked, stamped or branded, or labeled they shall not be admitted to entry."

Lindner's wares from March 1891 foward, and more than likely that of Suhl, wore several different terms for location including Saxony, Thuringia and possibly another before they found their identity when they settled on Prussia.

On May 19th, 1892, Germany saw the Reichstag pass the new German Proof law, which was made public on June 22nd, 1892. It became effective on April 1st, 1893 and this is the reason we see the Vorrat / onhand stamp of a V surmounted by a Crown. Since Lindner's Quality Control Stamp was that of a brace of Crossed Sidearms surmounted by a Crown, he was forced to change. This change looks to be @ the cusp of the new proof law and maybe he as just like us, a procrastinator up till the end and waited till he was obligated to do so? Anyway, the change of the Lindner Quality Control Stamp to HAL surmounted by a Crown was either in early 1893 or in April 1893 very close to Nr. 450(2nd Lindner Series), which may have a higher probability. What happens in between or betwixt the transition is the focus of the current data mining effort.
