Here is the ebay picture of the reverse side.

Can anyone explain why the mold design appears deformed in the are Ive marked in white, which just so happens corresponds exactly with the apparent drill hole position in 'anon's' scan.

'anon' must be a regular chipboard reader that was aware of my bulletin board. Someone that wants to help but is afraid to give their name. Perhaps they would be prepared to reveal themselves to the club president in confidence.

Something else has been puzzling me all day. The green 'baize' background to the ebay photos. Ive seen it many times before on ebay when viewing lots. Its a regular chip seller but I cant figure out who. Someone must recognise it?
