Hi Paul & Kevin
The mark on the bottom does have a shallow dip but I have been looking at it in the light to try to see the lines but am not sure what I am looking for or if there are lines running in the same direction- I think that is definately for an expert eye lol.
I recently purchased this off ebay for £11.57 as I liked it because it looked quite quirky with the skull & crossbones. The guy I bought it from told me that it was very old and that i'd bought a bargain so I was interested in finding out anything about it.
Thank you all again for helping - I shall keep on googling to see if I can find any more info
