The three movements in the K3 were what Yale described as modular. ________________________________________ From my-time-machines.net : True interchangeability where a technician could simply arrive with a movement of the same model as the malfunctioning one and could do a simple swap out came with the introduction of the model Triple L in 1892, designed to operate with a bolt motor and the Triple K for manual boltwork. Their movements were truly interchangeable. Multi movement locks would be consecutively numbered. Proof of full interchangeability with respect to the movements is the fact that most time locks seen in the collector's market today do not have consecutive serial numbers as they have had their movements swapped out during their time of service. This indicates that the time lock has a long service life to have had movements changed out. Consecutive numbers are always more desirable and usually indicate a lock that was in service a much shorter period of time. ________________________________________ As you can see from the pic I posted, my K3 has consecutively numbered movements.
