Some may tire of the continual supposition of the Lindner Daly marks as well as the why behind the Lindner-Daly doubles, but it appears that Heinrich Lindner's business expansion of 1903/1904, Ernst Lindner attaining the rank of master 1906/1907(guess due to age only) and the 1907 edition of the Schoverling, Daly & Gales catalogue are more than coincidence. Also some of the verbiage included in the catalogue is self lauding, but I think that a close examination of what is said may give insight as to what happened in the Lindner & Sauer shops.
from page 5: "Charles Daly Guns have the genuine Anson & Deeley System action, Charles Daly pattern, which means that the frame is one inch longer that the regular Anson & Deeley frame, making the leverage greater;"
from page 17: "Sauer Hammerless Guns are made with Anson & Deeley system locks, but with an inch longer frame, which makes the leverage greater. The lock parts are highly finished and the fitting is simply perfect."
I'm positive it's been covered before about the frame length but to me this seems to closely tie Lindner & Sauer, who addressed mechanization circa 1882 and by 1907 was pretty much fully dependent on electricity.
Also from page 17 on Sauer Hammerless Guns: "The boring is done on the most modern system adn the shooting guaranteed. And thanks to Geno it has been confirmed that the "Large & Small Crowns" denoted craftsmanship & shooting performance.
From page 7: "The engraving is done by our finest artisans, by hand only; sometimes months are devoted to engraving the actions, while the other parts are being finished in the different departments of the factory. Every gun is tested over and over again until it shoots perfectly, which accounts for the good reports we are constantly receiving of the shooting qualities of Charles Daly Guns."
The "Regent Diamond" had "a crown of gold worked in the action, the inside lock work finely finished and inspected with the greatest cares". I'm curious how the early "Crowns" found on the underside of the tubes with the "Cross Pistols" compared with the "Crown" on the underside of the "Regent Diamond" and if the "Crown" was to denote the mark of quality. Also considering the "Crown" over a backwards "E"B found on the underside of a set of tubes

and if of German origin along with the Sauer "Large & Small Crowns", would the mark of Lindner be a quality control mark as well as highest craftsmanship and shooting performance?
