The seller bought it from a technician/dealer a few months ago for about the price she's trying to get now (selling for personal reasons, not piano-related ones):

Looks like some sort of short studio. A P2? For the price it might be quite old.

Yamaha made Everett pianos during the time their plant in South Haven, Michigan was open The plant closd about 25 years ago, so the piano is pretty old, but the Everetts have a good reputation for durability. The price is not unreasonable if the piano is in good condition. It's worth a visit and an audition.

I have seen some Everett pianos but never one that said Yamaha on the fall board. Is this a picture of the piano that is for sale?

That's the actual picture. She has no idea what she bought.

Yamaha had an assembly plant in the Everett factory from the mid to late 1970's. The casework In the photo has some very American features.

If the lid opens freely, the action rails will be aluminum if Japanese and wooden if American. If the lid does not open freely on hinges, there are probably studs at the back which can be turned out with a hex wrench. That feature would make it typically an Everett school model.

The strung back would be the same manufacturer as the action. I don't think they ever made interchangeable scale designs.

Get a tech report.

I have several Everrett instruments that remain in use here. I would check the inside of this one as the cabinet is Everett but the decal is Yamaha. I have never come across this style of cabinet in a Yamaha.
The top slides horizontally backwards after removing the hex nuts mentioned.

I agree, the case is an Everett case. Perhaps the decal was changed to Yamaha?
