Was hoping you'd see this, Silverly, and use your skill to locate the image!
Is there a reason you believe Hamilton was a retailer? Personally, haven't seen any indication they were anything other than a wholesale manufacturer.
A size wasn't noted, but this appears to be a copy of the large berry spoon (9-1/8") in Kirk's 'Repousse' - given the less than crisp detailing and slight distortion of the pattern, along with what appear to be tiny pinhole casting flaws in the bowl and on the back, would suspect it was cast from a Kirk original (the slight difference in proportions likely due to camera angles).
