Andy,
as far as the Sauer is concerned, it is known sometimes as "Model 20" or "Model 24" (Model 25 is new to me - allthough.... why not!), depending on the assumed production start. It is (no matter what designation) no official, but a collector's term. Sauer's own terminology was always "Westentaschen-Modell", and later "Westentaschen-Modell alter Art" (vest pocket model old style). "Later" means, when the model 28 (now, an official term used by Sauer) came out in 1928. The model 24 runs from serial number 1 to 8540 approximately. Yours seems to have an odd feature I have noticed only on my own one serial number 7718 (60 away from yours): an "L" under the serial number - can that be? Not sure... what is the strange marking on the right side of the slide under "CAL. 6, 35" ??? Can't make it out....
..but would like to know for the collection of Sauer serial number data.
Dave: should you have meant me: I am honored. What's about posting pics of your new Sauer 1930? A 1930 in excellent condition will make me jeleaus! For sure!
Regards
Martin
