Cox Dealer Catalog???? Carou-sell..........

Great find Bob, very early PT-19! The first three years of production, the PT-19 used a black rubber spinner, likely from the TD-4. After February of ’63 it was switched to a red rubber and used until end of production. Also, of note was the new for ’58 Thimble-Drome ‘Dubl-Tuf’ nylon props with rounded tips, up to then Cox had been using Kay-Sun props or K&B ‘Plasticoat’ wooden props.

Good question.  I'll have to ask the fellow that has one hanging in his den room.  But I would think it was just a regular old Cox Medallion 15.

Found the answer we were looking for, Bob.

The larger Cox Piper Comanche C/L RTF used the Sportsman .15 engine.

This is the oldest one I have. It is 5"x3.5" scanned at 600 dpi. Unsure of year but no PT-19, I would guess late 50s.

Good one CB!
Interesting to see that the RR-1 was a buck cheaper than the Space Bug. Not so today.

And George, no wonder the .15 Comanche is so valued. A little more readable from your post.

The engine was also used as a product engine in the beautiful "Big Comanche" C/L model. This was the only .15 powered ready to fly C/L model Cox ever manufactured. Here, the engine was equipped with a longer needle valve and a spinner.
