I'd say it's an original Namco. Do you have more pictures?
Cornchip.
Modified post .....now I'm not certain. I have seen one of these recently. It had 'Namco' below the stick. I can't really see that in your picture. The cabinet does look identical.
Modified again. I think I have it. The cabinet is Kareteco (early) with the control from a (later) Kareteco Puckman. Not a Namco. The speaker slots are different (larger than a Namco original). It looks like it's in fairly decent condition. Wish I had one.
