What does this fit?
I saw a lot of these on ebay and gave them some consideration before deciding to buy the Seagull angle finder instead (genuine Pentax units to fit the later cameras are quite pricey, even second hand).
I think your seller either made a mistake or was genuinely misleading - hard to tell really...

It will also fit a K-series camera (KX, KM, K2, K1000).
Pentax changed the width of the fitting with the M-series cameras (making it a bit bigger).
The width has remained unchanged since though, so you can use M-series and later accessories on the digital bodies (I use an M-series finder myself).
Apparently the Olympus OM finders fit Pentax as well, although I've not tried this personally

Like Reuben, I agree that it is definitely for the Spotty series.
Put it back on eBay with the correct description and I'm sure it will sell.
Good Luck with finding one that fits!

It doesn't! Does anyone know what it does fit, when it was made and can I get a new adapter to fit my cameras?
