Mike, I was typing my response to your question at the same time as 'Whig'. Whig's fine information posted first.
I was not trying  to Speak Over his response, Kibitz, or Over-Kill with information.

FWIW:

'Local Boy' has been kind enough to loan me his interesting 'used' copy of Brophy's, "The Krag Rifle".

Bill Brophy signed that book for his friend and noted Krag authority, Bill Mook.

Bill Mook made blunt observations and notations for his own use. Both fine men are now deceased.
So, I see no harm in posting Mook's brief comment on Brophy's reference to the 'knob-less cocking piece' being exclusive to the model 1899 carbine.

(p.s. - A serial number range would allow KCA members to give helpful information to 'vet' this nice looking carbine).
