I have been working on this for a month or two now and I am about ready to put them for sale on titanpinball.com but I have run into a small hold up I thought the Pinside community might be able to help.
First, the product is intended to clean up the normally scratched up, nasty ol lock down bar receiver. They are usually pretty gross. I have a Funhouse in my garage that I didn't even want to post a picture of!
It seems like many things pinball, there is not complete consistency with the type of receiver used on identical runs of games. I think the only good way to be sure of what you are getting is good old visual identification. I'm working on putting together some images of various lock bar receivers to match to the decals that fit them. So far, I have the 2 pictured below: Late Williams/Bally/Midway and Data East/Stern. The W/B/M also fits Spooky, Multimorphic and I think Dutch Pinball as well.
The Data East/Stern I know fits at least SAM games and does not include the cutout for any Lock Bar buttons. I'm not sure is Sega used the same receiver or not.
Feel free to share lockbar receiver pics if you think you spot a difference! I am also currently working on older WPC (Funhouse and older I think ) as well as Williams System 11.
If they are in demand, I'll add classic Bally, and older Williams, Gottlieb, etc... Currently I am thinking around the $10 or less range.
