From a catalgoue reprint(Hermann Burgsmller) it appears that the name Shne was added in 1905. Quite a bit of info in the catalogue. Also there are several types of hammer drillings. Is it an underlever with a toplever Kugelsfellung; does it have a doll's head extension or not, or maybe a Greener crossbolt; what is the lock type; does it have a rear ocular or is there term Federleichi present?

Kind Regards,

Raimey
