Built by Mark for Mark, at Davidson in '85 or '86, I forget.

ST 59 cm to top (side of lug, not the point in front) (about 23¼")
   58 to center

TT 57 cm

HT 158.5 mm
Steerer 200.5 mm

frame weighs 1635 g = 3.60 lb
fork weighs   575 g = 1.27 lb
total        2210 g = 4.87 lb

TT is Prestige .8/.5 (1")
DT is Prestige single-butted .9/6 (intended as a seat tube), 
  butt at the HT end only
ST is Prestige .7/.4 double-butted (intended as a down tube)

Rear stays are Columbus SL.  
Seatstays are "biconico", capped with a thin piece of tubing
  - not the solid, heavy plugs used by many builders.
Right chainstay & seatstay are mooshed to a "D" section right at 
  the dropout for freewheel clearance - that isn't material ground 
  away (making them weak); the existing metal is shaped that way for 
  clearance.   

Fork blades are Prestige 
Steerer is unbutted Excell (French? Swiss? I forget... supposedly 
  some super-hi-strength steel)

Head lugs are Eisho, seat lug is Ohtsuya

BB shell & crown are Takahashi, cast by Hitachi (note the Hitachi 
  logo in the shell.

The crown, called "HNR" by Takahashi, for "Hitachi Nagasawa Road", 
  is normally solid and a good bit heavier.  I drilled it crosswise 
  with a 1/2" drill making it hollow, and lathe-turned the top down, 
  making a shoulder for the headset race seat and also further 
  lightening it. Note also the spot-facing on the front of the crown, 
  eliminating the need for the radius washer on the brake bolt

The front dropouts are plug-style, with the plugs hollow and drilled 
  through such that the vent hole is pressed up against the front hub 
  axle.  (With the vent at the very bottom like this, there is no way 
  for a puddle to form, if rainwater or condensation gets in.) These 
  are just about the lightest possible steel dropouts (though Art 
  Stump's hybrid steel/aluminum pieces are probably lighter).

Silver brazed except for the dropouts and the seatstay caps, which 
  are brass brazed.
