Can you check that patent date again?
Patents were issued on Tuesday, and 7-19-1928 is a Thursday.
If correct, then
CONN USA would definitely suggest it is not a foreign patent.
Maybe the manufacturer marked it with the date of application, and not the date of patent award -- which will make finding it very difficult.
Or, maybe it wasn't patented at all, and the manufacturer just claimed it was to avoid competition. (Which is not legal, but you have to get caught..)
