Here we have the ultra rare Twilight Zone pinball slot machine mod, This is the first 3 circuit slot machine mod which has been made available and is an improvement on all other designs, it houses 4 diodes, 2 x yellow which work in conjunction with the yellow "Spin Slot" bulb, 1 x white which illuminates the reel and 1 x blue which is active in "super slot" mode and when other shots are made (spiral etc). These are resin cast and 3D printed (original die casts have been unavailable for many years), these are only slot machine mods which are currently worth adding to your machine.
