I've gazed at the Witten steel stamp for some time and it appears that the term "Monopol" on the left tube is to be coupled with the term "Drilling" on the right tube and notes the model or a trademark, having little relationship with the steel type. I've seen single "T" stamps on tubes similar to the frame stamp and one guess for the mechanic would be Fritz Triebel of Zella Sankt Blasii. But as usual there are others like K. Terling of Zella-Mehlis as well as Fritz Thomas. The overall effort is a combination of individual efforts by the S.S. craftsman who may have performed the tube work and also was a barrel knitter with the T mechanic was an action guy. And this doesn't even begin to include a stab at the stock maker.
Kind Regards,
