It is an Anson & Deeley Body Action platform with cocking indicators made towards the end of WWI or the early 1920s in Suhl. The tubes were either sourced from Hänel where they were completed by the most competent mechanic Gebhard Helmuthhauser / Gebhard Helmuthäuser or Gebhard Helmuthäuser who was listed @ Bergstraße 1 or Gebhard Helmuthhauser / Gebhard Helmuthäuser or Gebhard Helmuthäuser was sourced for the tube work. There are some odd single >>K<<s on the tubes and the serial number is low so I would hazard a guess it was a Suhl young >>K<< mechanic that was trying to make some bread money @ the end of WWI.

Any monogram on the butt; logo on the floorplate or steel stamp?

Cheers,
