Rims
Marking Description
S The standard rim shape in the FCB line.  A comfortable shape with a mild bite,
  excellent 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" type cup shape. 
 
 
MVD
 A traditional "C" type cup shape based on a Bach
 
 MT VERNON NY 1 1/4C cup.  This is the most popular

orchestral cup.
 
 
MV
A traditional "C" type cup shape based on a Bach large
 
 letters 1 1/2C cup.
 
 
MC
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.  3C players love this cup.


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.
 
MS A shallower version of the M cup; facilitates a lighter sound,

quick response, and easier upper register.


S A very shallow and flat cup shape.  Best for players who

do not 'bottom out' on shallow cups and need to play in the

upper register only.
   
P Designed to work with the "P" rim for use on piccolo and for lead.

Not a super shallow cup, deeper than the M cup,

but the rim/cup shape aid the upper register.
Backbores - Trumpet
#1 - A compact and "tight" lead backbore. Comparable to some Jet-Tone backbores, works best with shallow and compact diameter cups. Stock throat is 28.

#2 - A compact lead backbore, comparable to Reeves lead backbores and Yamaha Shew Lead backbores. Works best with shallow and compact diameter cups. Stock throat is 28.

#3 - A versatile backbore with resistance for lead, yet is useful in a variety of situations.

#5 - A great commercial, lead backbore, or even all around backbore.  A "76" style shape. Most classical players looking for a pops type mouthpiece like this backbore.

#6 - A dark sounding backbore with great articulation.  A "7" style shape.

#7 - A "24" style shape that is a favorite of orchestral players. Based on the Yamaha Hagstrom backbore.

MTV - A "10" style shape that is a copy from an outstanding Mt. Vernon 1C.

#8 - A very consistent backbore - soft to loud and low to high, a "10" style shape.

#9 - A "57" style shape with a warm and broad sound. Works well on rotary trumpets. 

#10 - A "24" style shape, but with more flare in the second taper than the #7 - larger total volume.  Based on the Parke Orchestral backbore. Popular when combined with the MVD cup and used on C trumpet, often with a 24 throat.

#11 - A great piccolo backbore.  Some like this backbore for orchestral work, it stays warm when played loud, sounds big.  A "117" style shape.

#12 - A dark backbore that is also large, a "D" style shape.
