Well fellers heres the deal. At this point in time no one seems to definitivly know which company produced the actions for untold numbers of German makers. It is clear however, that Sauer did produce some frame forgings for the trade, as well as other components. Some folks SPECULATE that Sauer produced forgings for Lindner (Charles Daly) but offer no real proof. These Lindner forgings could have been produced by Krupp or simson or Merkel or Mauser (less likely) for all that we know. Lets be clear hear. Anyone that says that Sauer produced the actions for Linder is only offering opinion.

In regards to the Geyger action above, it is closer to a Linder type Action then a Sauer Action. Lindner actions usually seen having the large prominent screw in the middle of the minor frame panel AND cocking indicators thru the top of the frame.

As for the Elephant in this room (so to speak) Does your Geyger have the Lindner type of "Ejector eyes" on the sides of the forend? Can you post a picture of the frame and forend in place so that we can see if the forend does indeed have these aforementioned eyes or anchors? Danke and best.
