Older Adlake marked key marked for the Rock Island has near perfect pocket wear. These older CRI&P keys don't pop up as much any more. More desirable example to put in the collection having the big left handed curved Adlake. Roughly the time frame on these big curved Adlake would be 1920's to 1940's. Besides having the big Adlake on the back, serial number 45261 and S for switch. Both sides were deeply / nicely stamped showing near perfect pocket wear. Front has CRI&P RR with all letters still legible. Could be a nice upgrade for the collection, any questions please email me. J Har
