By ca. 1925 the Bell System had developed and used approximately 100 different types of transmitters since inception, according to BTL history, The Early Years.  601 is not one of the common types produced in large quantities.  Not long someone on the forum found a 606A transmitter, here.

Does the transmitter have a patent number on it?

Do you have an E2 handset?
I am waiting for an E2B to go along with my D5 handset mounting. The E2B handset used a high-efficiency receiver for use on long common-battery-signaling local or foreign exchange loops, but the transmitter was operated with a local battery and therefore it required separate cord leads isolated from the receiver. E2 handsets used a four-conductor handset cord, therefore, similar in principle to the later F2 handset on the 307 telephone.  The D5/E2 telephone type was the 206 with a 634-BB subscriber set.
