Up date on my recent visit to Perth museum, below is a clearer image of Monart piece with dimensions included and a image of the base, which is indicative of early Monart production( no grinding of outer ring). The colour code is 162.
This piece is 33cm (13inches) tall and the one in the Monart catalogue is 23cm (9 inches), without other pieces to compare and measure against, it will be difficult to say if this one is an unrecorded shape or a variation of the Monart SC shape.
Does any member have a Monart shape SC ?, if so would it be possible to measure the piece to compare with this one.
