Wow - Randy - just WOW!!!
For clarification - Oscar made an exact DOT repro spinner for roughly the same price IMS. He had a black anodized knob that was also almost a repro of the original and the spinner was about the same price (maybe in the $160 range, not sure, also not sure if that included the knob - details
here.)
Differences are obvious.
Apache also made one, but I don't know the details on it.
As for games, D.O.T., Zwackery, and Forgotten Worlds uses the push, but no pull. Forgotten Worlds has 1 or 2 players, one spinner per player.
..and then, of course, there are still all the regular spinner games.
Just for clarification - D.O.T.
did use the Pull function, the other mentioned games did not.
Tin Star, Wild Western, and Front Line used a cam actuated by a spinner knob, which looked liked a spinner with push action, but was actually more accurately an 8-way joystick that was always in one position. However, I believe older versions of mame were using a spinner to map this and if you can do that in newer versions, this would work great for that.
Also, while not accurate, Ikari Warriors and other rotary joystick games used an 8-way joystick that you could rotate the handle to turn the player to fire in a different direction than you were moving, and then fire and grenade buttons, but without the authentic joysticks it is hard to play. You can do it with a Tron style trigger and thumb stick and a standard spinner, but I think using one of these with a standard joystick and push to fire and pull to throw grenade might feel more natural - at least it would get the buttons on the correct hand.
