The Scotty Dog seal press was made in the British Isles. Best Estimate for manufacture is between 1920-1940. Seal Presses in general are not considered "cute" however the Scotty seal defines Cuteness.
Of the dozen or so known Scotty presses there appears to be different color schemes
Most British seal presses are in the rectangular form
Each appears to be hand finished, note the black and the red collars.
For a size comparison an American Bison press is compared to its British counterparts
The seal to the right is the only one to still have its marking on the back. It reads Reg Design No 836 5???
Misdescribed by unknowledgeable sellers as an American Hubley, this very British mark disproves any American connection
These stylish and ornamental Presses are unique amongst cast iron seal presses
The black collar Scotty seal has a British Isles address
While this is an "American Address" its form and addition of USA this appears someone most likely routinely posted mail from the UK to America
