Hi Trevor, many thanks for your response. I think you may be onto something here! What I could see was a G with a W on the tail of it and once your head is set on what you think it is, it's hard to change your mind, but I can now see GS and my W is just a wavy end on the G. The "94" to me were more initials (maybe DE) but it does have a 94 look to it when it's pointed out, as you have done. Thanks again! Kind regards, Barry
