My 'Perfection' frame is now with an artist who promises (at great expense !) to reproduce the decal as a flat line drawing which I will supply to Steve at Lloyd's. Once I have a scan of then line drawing I will post it on here also.
It now appears that the 'queried' script design has turned up on a 1930's machine, so we now have 3 script designs for Grubb machines that are before the Holdsworth script design.
