Quoted from The_Director:
Just noticed something weird on the field I swapped. It doesn’t have the numbers for the banks ABCD and only has the bank letters in the middle. Early run? Proto? I just noticed, but strange and have never seen.

They don't need to be on those inserts. You have the A-B-C-D play field. So you have A-orange, A-red, A-blue, A-green. And all four of those are located at...
I wish my Play field was the A-B-C-D type. They are scarce. But they are out there.
Way back in the thread someone explained the logic behind the A-B-C-D play fields.
Of course, it you are upgrading with a CPR repro play field, you will give up the A-B-C-D format, since CPR followed the Magic Square format.
When you have the number type play field you have to do a mental exercise as to where Red-7 goes to. Eventually, after you play enough and your memory function kicks in you realize that Red-7 goes to "C". And blue-5 goes to "A".
