Identification Please

Attached is a picture of some cowls to SIG models. But which ones? Dusty, SIG label on inside, and of some sort of thin fiberglass is only thing I know at this point.

Light one at top is biggest, and possibly designed for an inverted one banger. Middle one looks like to be designed around some opposed Lycoming design, that narrows at the rear. The bottom one is smallest, rather cone shaped and round overall, and may have been for a .09 or .049 powered aircraft.

Any one have an idea as to what model they were to fit then?

The top ones look like the Chipmunk or Zlin cowls, possibly for the C/L Stunt models. The middle ones look like there the Super Chipmunk C/L Stunt model. The little ones I don't know.

I agree with stuntflyer on the Chipmunks... Bottom one looks more like some sort of universal.
