I thought that cert could be gotten extra ONLY for experimental light

That's not true. The first registrant of an amateur-built experimental
may apply for (and will probably receive) a repairmans certificate
applying only to that aircraft. The only real privilege it confers is
that of conducting the annual condition inspection. See the rah FAQs
for cites.

Thanks, Bob K.
