On the weights n things web site to look at previous sales look at a weight which they have sold on the right hand side of the picture it should have a PDF icon which you can click on my Adobe 6.0 reads it ok.
The one they sold was unsigned, i'm just glad I have come on here and found out some good info about this weight. I have a bit more understanding now of these weights, 3 day's ago I was totally clueless I could of sold it on for £20 to someone who knew what it is actually worth and they would of got a bargain.
Thanks for all your replies, I can understand why people collect these weights some are extremely eye catching and beautiful to look at. Shame air con was invented you would probaly see a lot more of these in the office on a hot day with the windows open. :hi:
