Western Electric Transmitter Numbers

As usual for me probably too much - $229.39 - although this is a rare early beveled edge transmitter.
Now I just have to find a phone to put it on, can't leave it on this:

The transmitter is worth around $200 itself, and the rest of the phone is worth about $50-60.  Not bad.  If I had noticed it I probably would have bought it for that price.

Unusual transmitter.  D 6432

On newer WE phones, D and F numbers seem to indicate a small production run.
I wonder if this is a from a small production run?

Given the number of transmitters available - high current, low current, ultra sensitive, etc, one wonders what new variation would warrant a special production run at all.

I was thinking of  proto-type/field trial reasons.

Same comment really, after all the time and all the transmitters, what else is there to test?

This one is on a 20AL with 1915 patent on base so not necessarily original to the phone.
