Quoted from Mr_Tantrum:Thanks for the input. I should have gotten a close-up of the tag at the top left of the pachinko. Also, does the center logo tell you anything? Looks like it says "Conic".
The pachinko machine is made by a company called Ginza. It is the Comic model. Hard to tell the exact year without seeing the tax sticker in the upper left of the machine, but looks to be mid-1950's.
