Bosch (AL 33X) >Alternator?

the bosch booklet i have describes the Type designation this way:

on each alternator (somewhere), there is a Type number like this:

TLM( )28v62A11
which breaks down this way:
T - stator frame diameter:
      E=80 to 90 mm
      G= 100 to 109mm
      J= 110 to 119mm
      K=120 to 139mm
      Q=140 to 169mm
      T=170 to 199mm
      U=over 200mm

L - fan installed
     W - watertight (Syncros might have this?)
     Z - railroad (locomotive generators (!!???)

M - fitted with intensified interference suppressors
     A, C, D, F, G, H, V = no uniform arrangement of
       characteristics for all stator frame diamters  (!!??)

( ) = direction of rotation (viewed looking onto the end of the
         generator opposite the commutator end)
         -> or R = clockwise rotation
         <- or L = counterclockwise rotation

28V = generator voltage in volts

62A = maximum current in amperes

11 = speed in 100 rev/min at 2/3 maximum current.
       (so at 1100 rpm, the alternator is putting out 0.67 times its
max current).

hope that helps. :) don't see that particular model listed, but this
is an old book.
