FTR Technical Bulletin No. 003

Re-pinning of selector barrel (FTR-260)

On a few occasions during the 2002 season, the pins within the selector barrel failed. The specification of the pin was

immediately increased and as an act of good faith, for the past year, all barrels returned to the factory have been re-

pinned FOC.

While this service will continue to be available it will, with effect from this bulletin, cease be FOC.

A charge of £50.00 will be made for each barrel returned to Hewland Engineering for re-pinning. Alternatively replace-

ment pins (part # DOW-033) are available through your normal Hewland supplier.
