I think it must have been well cared for

It came from a house clearance along with some other art deco items, all of which were in pristine, untouched condition, so I think they might have been wedding presents packed straight into a cupboard and never used for the next 70 years or so.
I didn't think it was such a good match for the Hermanova hut plate, because mine only has 8 spokes to the pattern, where the one on the cd has 12, and the one pictured on the cd has much more of a curve to the plate edge too? The pattern is very similar though apart from the number of spokes.
