[TR] tr-6 surrey top?

[Gary Nafziger]

Just received my 6-pack newsletter/mag. and noticed in the article "Patients
Aid Doctor" pg. 12 that Ken Dolhonde is standing beside his tr-6 surrey top. 
I've seen pictures of these on tr-4's but never a tr-6.  Were they available
and do they ever show up at car shows?  I've never seen one before in a
picture or at a show.  Just wondering if they ever come available to buy.
thanks!
