I don't believe it's Coquille, either. At least, I haven't seen anything Coquille remotely like it. Coquille is usually signed on the base in two places: one says "Coquille" and sometimes the date, and on the other side of the base it says "Flygsfors" or "Kedelv." It's very easy to get a dremel marker and write Coquille on the bottom, but that don't make it so. It's not Chalet, but I agree it could be Altaglass, though how it got out of Canada I don't know. There is quite a strong group of Altaglass collectors in Canada, which probably makes it worth more as Altaglass than as pretend Coquille.
Good luck.
