Up for sale is a  RR KK Keen Kutter lock used on the FRISCO Rail Road Line. Key works fine. The shackle locks but there is a bow to it. The Keen Kutter Locks were NOT the most heavy duty locks and they got a work out on the Rail Road. When they broke I’ve always heard stories the railroad workers just tossed the locks into the river or along the tracks. I’m sure many are buried along the Railways and in streams and rivers.

 Looking in Frank Arnall's "The Padlock Collector" 6th Edition 1996 value guide this lock is listed for $700. Pg 213 #12.

 Some other RR Keen Kutter Padlocks were Santa Fe DR&G Denver Rio Grand.

Asking $700... 1996 price guide. O.B.O.
