Tee Dee Question, test your memory

I am trying to estimate the age of a new Kirn-Kraft Tee Dee .049.

The .049 Tee Dee has the screen on the venturi. And it was sold for
$17.00 by Kirn Kraft.

When did Cox start selling TD's with the screen on the venturi?

When did D. Kirn sell his business to Kustom Kraftsmanship?

Thank You.

Actually I have done quite a bit of research already, and found more information
at AMA's Hall of Fame, and other RCG members. MH's collection seems too new,
and incomplete. Dale Kirn gets credit for some designs, but there is no mention of
Kirn Kraft modified Cox TD engines for FF & CL.

He briefly mentions Kustom Kraftsmanship, but the fine needles, pressure port back
plate, and engine mods were originally developed and sold by Kirn Kraft.

Right now it's curiosity. I was given a collection of engines by a good friend.
Nearly all the engines were won from club raffles, and so they are in their
original boxes. And they were acquired without a predetermined purpose.

By far the majority of these Kirn Kraft competition engines were used in an era when
running high nitro mixtures like 65% Nitro, 15% Propylene Oxide, 20% Oil, FF and CL
contests. And No Methanol! Literally twice the nitro content most people would use
these days.

Finding a NIB Kirn Kraft modified engine is a real find, and is similar to being on
Antique Road Show.

Capt. Quirk,

You are so right about the high nitro days, I remember them well. Kirn Kraft was started in the Mid 60's and sold to Joe Klause in the early 70's (as Kustom Kraftsmanship) if memory serves me correctly. Now it looks like that went to Competition Models which appears to be gone.

I didnt even know that tee dee's came with kirn kraft parts in the 70's. We would just buy the kirn kraft fine needle assemblies and pressure back plates separately, and install them ourselves.

I know that Dale made and marketed a variety of parts, and that he modified engines on an individual basis, but I didn't know that he marketed complete modified engines to the general public.

You say your engine is "NIB". Could you post a picture of your engine, and any packaging/paperwork that came with it?

Is there a serial number or other ID scribed onto the case or the like?

Oops, I just saw that this thread is several months old.

Capt. Quirk, if you're still around though, I'd still like to see a picture of an "NIB Kirn Kraft Tee Dee .049"...
