For Generation two keys that is correct.
Compare a generation two and the replacement generation three key.
Gen two Key A = Q-D / B-S / KB-S / Q-DM / K-DS / QB-M
Gen three Key 1 = Q-DS / B-S / KB-DS / Q-DM / K-DS / QB-M
The generation three key has a 10 degree cut in space 1 AFT (DS rather than D) and 3 AFT (DS rather than S). This would work fine on a Medeco generation two lock as well. It also tells me Medeco allowed cuts in those spaces for generation three that were not allowed in generation two. Specifically they allowed a right 20 degree cut in space 1 AFT and a center AFT cut in space three. So Mr. Tobias had to alter the bumpkeys to allow them to set the sidebar on those newly allowed angles.
