Hi. I am new to Pachinko machines and got one from a sale. I think I have determined it expired in 1979. But I can find little other information on New Gin machines, especially this one as it says Special Elec on the front. It has 2 gondolas, 5 spinners, and 4 tulips. Its in really good condition, just a little rust on some of the screws on the back. All the nails are there and there is no discoloration on the backing graphics. Can anyone tell me where I can find some more info on this machine? Especially its value. Thanks so much.
