I'm not familiar with Jos Zeller, unfortunately. There are those who will be and hopefully will be along soon to answer your question. A good set of pictures of all proofs and of the drilling in total will be a great help in making any determinations. I would suspect the trigger guard is probably horn rather than bone...but I am frequently wrong. The 9.3 X 74R is a fine cartridge and with the einstecklauf, (insert), I think you have as near a perfect combination as can be had.
