Large Chamber and was probably a standard MPC sold with the horn and standard tip opening of the time. Facing and Rails are perfect. Body shows some discolouration and slightly green age look. Plays as you would expect big deep sound from large chamber. Responsive and articulate. Plays nicely on my 1935 Conn 10. Just need to tidy up my bag and now playing a Ed Pillinger LA 7* which has similar sound and that I want to focus on.
