| Hey Larry,
Yes, I think the M is for medium. It sure doesn't play like a medium though! I've played big horns all my life (except the schilke) and this horn sounds alot bigger than my large bore Benge.
My mpc is a little difficult to describe right now. Originally it was a Reeves 692s which I think is more like a 41 or 43 with a #5 sleeve. When I bought the Schilke the Reeves mpc just wasn't working well ( gap problem I think) all that to say...Scott Lasky (with Schilke at the time) copied my Reeves to fit the S42. It worked GREAT, although It wasn't an exact copy, but it was close and I liked it. Well, I completely wore that one out and Schilke built me another one about a year ago based on my original Reeves. That probably doesn't answer your question very well, but that's what I'm playing on now.
