Atte Scheibenwaffen (Vol#1) has a good discussion of C. Buchel and his rifles. It seems as if he preferred hammer actions but the "Concurrenz" and "Martini" models both used striker actions. The illustrations in the book and in the "feuerbixler link" both show that in the "Concurrenz model", a lever extension retracts the firing pin/striker immediately as the lever is pushed down. The book illustration of the "Martini model" looks exactly like my action but only shows the striker and not the cocking details.
Mike,
I think that you may be correct, as there is no evidence on the current parts for a missing part. The unsuccessful repair may have been limited to the firing pin and possibly the striker hammer which could explain the lock up after firing, the bent lever and the incorrect sear angle.
The chamber rim has been lengthened to allow 8.15X46R cartridges to be formed from 30-30 brass without thinning the rim. This has caused the firing pin strike to be off center which may also contribute to the difficult primer ignition.
An inertial firing pin that extended all the way back to the striker hammer gave only a modest primer strike and no ignition. I did try a very strong main spring but haven't tried pistol primers.
I think that I made have to consider modifying this action.
