This cartridge is like the 10.3mm Clark discussed below. It was entered into the Austrian Military trials of 1887 by American Designer Col. Henry F. Clark. It had a complicated bullet design with a paper patched lead bullet with conical tip and lubricated on the front part of the bullet and the case cripmed almost to the tip, much like the Italian Vetterli guard loadings. The idea did not work, as there were more than the average amount of fouling and his design never went anywhere else than an experiment. According to Motz Vol.1 p.86, the cases were made in all probability by either Roth or K&C, but the “E” in the headstamp might also indicate Eisler & Co. of Vienna, which would seem odd, as they only manufactured ammunition for a short period. See also Motz & Kohlmann Vol. 3 p. 249. (Roth #U98A).
