Notes
Note the clear glass centre.
Reference materials do not identify the manufacturer of this juicer. I believe this juicer may have been made in New Zealand. I base this belief on the colour varieties seen in New Zealand, including, white milk glass and red glazed (or powder coated). If made in New Zealand the Crown Crystal Glass is the most likely manufacturer. If not made in New Zealand then New Zealand clearly was a major market.
