Serial No. 10109 ... from around 1974.

All original paint and decals, still in very nice condition.

I believe the Reynolds 531 decals with the gold bands stating: "Reynolds Tube Co, Ltd" were first issued in 1973, but may have appeared only later on many biikes if a manufacturer had ample stockpiles of the earlier versions. These were used until around 1977 when they were changed to include the "TI" logo - to reflect Reynolds' ownership by the parent company, Tube Investments Group.

{Don't worry... since taking this photo, I've changed the seatpost and saddle and pedals to less distractingly modern components.}

If anyone wishes to compare lugwork and construction details with those of their own BJ bikes, I have many more photos of this bike which can be viewed here:
