Shorthorn Semen Code - Columbus?

Does anyone have any Columbus semen and if so what is the code on the cane top? I have some vials and they are extremely hard to read so was hoping the cane top might provide a clue.

All the Columbus semen I am aware of simply has COL as the cane code.  If you go to the Heritage Shorthorn Society website (www.heritageshorthorn.org), a lot of old Shorthorn Heritage bull semen codes are listed in the Shorthorn Information section, under semen codes.  More are added as information is provided to the Heritage Shorthorn Society.

Mine came from multiple sources and all of it has COL on it.

Thanks I think that is it then - flip what I wrote around - 102 - and it could be read as COl. The 2 did look a bit funny, and I didn't clue in. Thanks for the heads up form the Heritage Shorthorn people.
