Kevin, it's just been noted on the Firepower club thread that the prototype Firepowers with drop targets had different plastics as well.
The two drop target prototype plastics were smaller than production plastics to suit the drop target set up, the bigger production plastics have a blue area which was added on to the front edge of the plastics for the stand up target set up. Their is no blue on the prototypes. Also, the left target plastic has the word "try" on it, production plastics are blank in that area.
You had done switch cut outs on your playfields with a view of a drop target retrofit option.
Is it now possible to easily create the additional two prototype plastics & add them to a standard set or even made to order?
Here is how the prototype plastics look...

And here the difference with the larger target production plastics can be seen on the retrofit, doesn't look quite right overhanging in comparison to how the prototypes look.
