fraserdouble,
good news !
i called around this morning on phone and find a man who knows a lot off Otto Geyger.He told me that Otto Geyger Rifles has been manufactured by Oskar Merkel in Suhl and they are all of very high quality.
Is there a little gotic "M " somewhere on the action?
Is there somewhere written "Mercator " on barrels ore action ?
He need all the stamps and signs on the gun.unfortunately he don't speak english.if you would send some pictures in good quality to me,also some pictures with all the stamps, i can show them to this man and will get closer information back to you.
