Portland Talking Machine Co.?

I agree- $200 to $250, though your case is a bit nicer than many of them. The arm & other parts were ordered from the General Phonograph Supply Co. operated by Otto Heinemann, they are good quality.

This off brand looks like a Meteor/ Stradivara/ Mandel variety machine. Yours is probably a very rare labeling variant, but "rare" doesn't always translate into "valuable" (ask me how I know! ) A collector from Portland might be interested just because it's from Portland.

It likely has a Heinemann motor. They're good machines, but unfortunately, not worth much more than the $200- 250 estimate already thrown out there. What's nice about it is the sound box swivels so that either lateral or vertical cut records may be played... if you have the correct stylus.
