Rims
Marking Description
S The standard rim shape in the FCB line.  A comfortable shape 
  aiding articulation, flexability, and endurance. 
O An "orchestral" rim shape with more (sharper) bite than the "S" rim. Comparable
to a 1X or Parke style rim.
   
W Similar to the Standard rim, but slightly wider.
   
P Designed for use with the "P" cup for piccolo.  A comfortable 
  and broad shape that aids the upper register.  It also works 
  great as a lead rim.
Cups
Marking Description
D A deep cup, very dark on trumpet, great for cornet.
   
MD A deep "B" style cup shape.
MVD A traditional "C" type cup shape based on a Bach
MT VERNON NY 1 1/4C cup.
MV A traditional "C" type cup shape based on a Bach large
letters 1 1/2C cup.
MC The standard cup shape in the FCB line.  An efficient cup
  with a quick response and vibrant sound. Similar in
   size to a traditional "C" cup, but with a steeper initial
slope into the cup and a flatter bottom with a larger throat
entrance.
M Shallower than the standard cup and versatile; facilitates a 
  lighter sound, quick response, easier upper register, yet still
  has a full tone and a low register that barks.
   
P Designed to work with the "P" rim for use on piccolo and for lead.
Not a super shallow cup, but the rim/cup aid the upper register.
Backbores - Cornet
#7 - A Great all around backbore.

#8 - Very consistent from soft to loud and low to high with great pitch.

#11 - A great piccolo backbore. A "117" style shape.
