The Made in Germany dictates (U.S.A. Trade Law) that it was made for the American market and post 1921. It is most probably a Schuler gun as he took over building guns for Daly when Lindner retired in 1917.
It should have a five digit serial number of somewhere around 25000 and up.
It should be of very good quality as Lindner was still Daly's agent in Suhl and approved the Daly guns.
It would be an almost unheard of Sauer gun if it does not have a Sauer mark.
Best,
