thanks jp. In fact I think my picture is a little misleading - the pontil is not really edge to edge, quite large but not that big. Re the reference to W/Fs., and yes I had heard that also, but didn't want to say so, as I have made some errors in that department in recent times. Webb's is a possibility, and I do know that Stuart produced some very large pontil marks. Anyway, seems the jury is remains undecided. thanks again.
