This is a quote from myself in earlier part of this thread " I am in no doubt that Kevins Ysart bottle is not the Monart shape HE. ", I would like to retract that statement, further research into the variance of particular Monart shapes, it has shown me there can be a wide variance in dimensions from two pieces with the same shape and size code, which opens up the possibility of Kevins bottle being the shape HE.
I still believe this was not a regular Monart production piece, for the reasons give earlier in this thread "the positioning of the canes are poor, they are up and down and not in a straight row and not what one would except in a piece of Monart"
