Hi Les, I cannot see why no-one has commented yet, I looked last evening but did not have time to do more.
That is quite an amazing egg you have their, not quite as big as an ostrich, probably about the size of an emu. You need to get together with Les (gwyntog) - see his post '... and on a lighter note!', I think he could do you a nice range in eggcups.
But more seriously, the curve running through it is great, long and sweeping delivery an excellent (eggcellent!) shape, not quite sure how you might have held it to finish the bottom. Has the growth wood (lighter side) given an issues as it dries?
