Definitely an export model; 115 volts notwithstanding. Philco did not use metal tags on their 1930s radios intended for sale within the USA, they used the gold foil stickers instead. (And from the 1935 model year on, the blue stickers with white border and lettering; green for battery sets; black for AC/DC sets).

I do not know why they chose to use metal tags on their export models.

Maybe some countries required a more permanent model tag? (That's another SWAG.)
