With no markings my guess would be a home-brew three dialer, but it sure looks awfully clean and we'd need to see a picture of the inside. Probably uses 01A tubes that (if good) are worth at least $10 each, depending on type.
These sets are a ball to play with. From the mid-twenties you can use ten 9 volt batteries for the B supply and a 6 volt battery or power supply for the A supply. These sets used headphones or a horn (or cone) speaker. You can buy a power supply for about $55 from AES:

Get a picture of the inside and measure the filaments of the tubes to make sure someone didn't stick in duds for display. While $115 is high, with good tubes $75 might not be unreasonable if it as clean inside as outside.
