Extra holes in some Western Electric 500 bases - what were they for??

[Dan/Panther]

I recalled a field trial 500 with a tone ringer in it. I thought that might fit those holes but I finally found a picture and that is a totally different base. There are other field trials that I could not find a picture of the bottom but I am thinking those holes might be there.

Harry do you have more photos of that phone ?

Paul;
Thank You.
I even responded to the thread. I guess that "Oldtimers" is kicking in.

I understand completely. I was surprised I remembered it!
