Only two known to exist, the other you'll find in a picture on the back page of Paul Barnetts book demilled (cut up). Mc Keever Daleys are rare as Paul Barnett said in his book especially with such an early serial number as 107.
The entire cannon is original. All three sets of serial numbers match, end of the barrel, left handle at rear of cannon and on the brass identification plate.
The elevation pin, the axle, and even the rusted chain that holds the elevation pin on the right side. The serial number is 107 so it was probably made in the 20's or 30' so definitely a pre-wartime piece.
Stamped on the end of the barrel are the inspector's initials JRB with USCG (United States Coast Guard) stamped and HYH (Huntington Yacht Harbor). The fuse hole screw is bronze and original.The bore is spotless see photo with my light down the bore, you can even see the threading of the fuse screw that comes in from the top. Barrel is about 28" long, carriage is about 26" long with about 12" wide and with the cannon at a 45 degree its about 19" tall. Steel Lyle cannons are rated for a thousand foot firing distance.
That usually equates to about a thousand grains. Recoils on Lyle cannons are huge, stand to the right or left when firing. The item "Lyle Line throwing Cannon Mc Keever Daley" is in sale since Sunday, February 23, 2020.
