Hi Ed,

Thanks for the additional information. I am sure that a perusal of various books etc. will turn up many more examples of these markings. I agreethat the last digit is an 8 too.

Artie Bob, your expertise is requested!

Cheers,

David

PS: Ed, Just a small word of thanks and appreciation for your scouring of the webpages all these years and sharing these little treasures with us all.
