and they came out in the same time:

Manlicher Schönauer M 1900

and

Haenel M 1900

clear timeframe - 1898 the Modell 98 come to light - every other bolt action is obsolete
Steyr and Haenel scratching heads and start to develope an action that can compete

btw. Axel , take a look what old C.G.Haenel documents are in the Thüringen Landesarchiv - state archive
http://www.archive-in-thueringen.de/de/findbuch/view/bestand/23622/systematik/51225

time to send someone there

wonder if we know everything about the haenel now, caliber were 6,5x57, 7x57, 8x57, 9x57 and 10,75x68
