Nice little gem that doesn't pop up too often from the MoPac railroad. Key has nice to moderate pocket wear with all the marks still show well. Front has MoPac deeply stamped. Back side has the Fraim dogbone dating it around 1910 -1920's I believe. Also has M-W for Maintenance of Way on the older dated keys. The newer ones have the Hallmark, missing the M-W. Could be an upgrade for the collection having an older marked M of Way key.
