I believe this question was asked before on one of the lists and if I remember
correctly the first few of the CC-32 and the BC-34 did not have the 10 & 12
inch stop buttons. Edison was planning on making 12 inch records which he
never did. All the BC-34 consoles I have seen had them and the CC-32 I owned
did as well.
I would ask Ron D about the governor. Both machines I mentioned above came out
April 1922 according to the Frow book.
