TJ Cycles (Trevor Jarvis Flying Gate) Frame.
Serial # 83239(?).  Number carved by hand in the bottom bracket.  Reynolds 531 DB.  I assume this is a 1983 build.  Dovedale lugs and Reynolds 531 ST tubing.  The Trevor Jarvis Flying Gate was a copy of a Baines Flying Gate model made from 1936-1954.  The Trevor Jarvis model was made from 1979 and continues today.

This bike belongs to Ken Wallace.
