Thanks for the prompt reply, especially on this day. Silly question, but how do I tell the year of the the manufacture? All I see are the numbers I have listed. However, about 1/8" under the numbers there is a stamping about 1/16" that resembles a bird head, sort of shaped like a "P", but it does not appear to be one. I have looked at Old Smithy's site, and I see a definite letter under the numbers in the same size (which I have learned designates the lot of manufacture). This bayonet has no such marking. Hmmmmmm.............

As soon as I can get my camera back from my son, I will post a picture. Again, the "bird head" stamping is extremely small and I am not sure if the qualify of my camera will pick it up.

Is there an answer to the mystery?
