Restrictor body
A front fork restrictor body, PN 97-1893, used in the telescopic fork damping setup on certain 1966-1967 U.S.A.-spec Triumph forks.
The restrictor body, PN 97-1893 (also listed as H1893), is a front fork internal part that shows up in the telescopic fork figures for the U.S.A. T100C, T100R, TR6C, and T120TT models in the 1966-1967 catalogs. It's part of the damping arrangement inside the fork legs on these machines.

Because it's cataloged specifically under the U.S.A.-market fork figures for these models, this looks to be a fork internal fitted to certain export-spec forks rather than a universal part across the whole front fork lineup. The catalog entry itself is brief beyond naming the part and where it appears.
If you're rebuilding a fork on one of these machines and need to confirm this is the right restrictor body for your particular leg, call the shop and we'll check it against your fork internals before you order.
