Switzerland: J. Muller. Of Diessenhofen.
Its is quiet difficult to date this deck with certainty as J Muller moved his factory to Schaffhausen from Diessenhofen in 1863 but continued to print cards with the Diessenhofen name until 1873. So they were probably made prior to 1873. Although they could be earlier as Mann: "All Cards on the Table" page 169, tells us J Muller began making cards in Diessenhofen in 1835 and they made a standard pack of cards with these aces in 1860. There is a pack in the Spielkarte Museum in Munich that is similar to this one and the "Cartorama" catalogue N0 65 of 2017 had a pack for sale with one card missing. The design is known as the "Swiss Cantons Pattern" and has reversible aces showing two swiss scenes and reversible courts, each end representing a different Canton. The pattern was also made by Wust and Dondorf, Fournier 123/124, and J Muller's ancestors were still making them a hundred years after this one, so they are reasonably common. This "Diessenhofen" pack, however, turns up far less frequently. Unfortunately there are two cards missing the 5 spades and 4 diamonds, and a few of the numerical cards have smudges or marks, worst shown, but overall the pack is in very good condition. No box.
