The imprimatur signifying keirin certification (NJS logo) appears
neither on the packaging nor on any of the chain's links. This model
is _not_ approved for professional keirin use.

Except for the dustcap, the pedal in the photos is a dead ringer for
the MKS "Sylvan Track", which does not have pro keirin credentials.
However, a closeup of the rear cage shows it to actually be a MKS
"Unique Custom" model, whose rear cage is stamped with the NJS logo
(upper right of cage), signifying that it does, in fact, have keirin
certification.

The Sylvan Track and Unique Custom models are quite good values, but
few people will mistake their finish, bearing quality and weight with
one of MKS' premium track pedals like the RX-1, Custom Nuevo or Royal
Nuevo.

sorry, guess i should have noted that mid photo far right, one (&
only one) link has what looks like the NJS circle(?).

the Sylvan are OK but i think the spindle bends a little too
easily. the Unique Custom might address this issue.

That's a JIS symbol, seen here on the left side of the wrench flat on
the axle of a MKS Custom Unique pedal in this picture:

The NJS logo is seen at the right of the same pedal's rear cage plate
