Rob, this station is usually cataloged as the Fandor (Josef Kraus) #2047, see here for documentation (scroll down on the page). However, Fandor also provided it to Dorfan to sell. The station came in several variations which affect the value. Some were embossed with stone sides, some smooth walls. Some were lithographed, others enameled. The early versions were set up with candle holders in them, later versions were electrified. Many suffer from extreme paint flaking. The reference link shows photos of several variations.
The pictures you show look like an embossed, hand-painted one, all original, with minimal paint flaking. It is missing the telegraph poles on the roof, but that's not unusual, - in fact finding one with the roof telegraph equipment intact is scarce. I have paid $100 to $300 for versions of this station; at a lively auction, yours might bring 250 on a good day, or you might get it for 150.
It's a nice station, originally designed for Gauge 1, it has a substantial presence on the layout without taking up inordinate amounts of space, which makes it ideal for Standard Gauge.
