He is asking about the 12 pound mountain howitzer chamber's diameter. It seems like you're looking at the diagram for the 12 pound field howitzer.

My understanding is that it is not significantly different. i. e., 3. 67" or 3.75" depending on the source.

The diagram I posted is of mountain howitzer rounds.
