I can't say this Fritz Wagner peddled example in Altenburg was sourced from August Schler but it looks similar to a August Schler example and from the same period was well as a serial number in the 24k range. But I don't see any RW stamps on the water table and there isn't an image of the area of the tubes from the flat to the forend hanger. I'm sure there were other concerns which were in the 20k range also.
Interesting how the Imperial Eagle die struck on the underside of the right tube.
Kind Regards,
