Hey, does anybody know if ACF ever produced cups that they did not have the brand on the bottom? I am a fan of their cups, and picked up 7 of then yesterday, one of which had the standard ACF made in Italy embossing on the bottom, and the rest of which were unmarked. The thing is, they all seem to be the same exact quality and dimensions. They all weigh the same +- 3 or 4 grams. Anybody know? The unmarked saucers that came with them seem ACF quality but weigh about 20 grams less than the others I have. The upper part with the rim is noticeably thinner.

The glaze is exactly the same, but I think that brown glaze was standardized long ago.
