If you can't find a kit, and plans will do, here is the site that a guy put together with the history of all SIG kits and the plans are there for download.

I think It's basically based on the original Chipmunk wing and a Super Chipmunk rib kit will get you that far. Don't know about canopies.

Thanks Dan,
I did didn’t know this site existed. I’ve built almost every models show on this site some of them many times lol. Just for fun the Snipper we would build them in lots of 10 and fly combat out the back door of the warehouse, we had a blast doing this. In the 20 some years of working at Sig I’ve had the pleasure of building and flying and designing many of these models (along with the FF and RC models). (In case you interested Dan and I met a long time ago flying RC sailplanes). Dan and his young son showed up at our first C/L contest at Sig. I was so impressed with Shawn I gave him an Acromaster just for being there, it was a hoot!
I did noticed that nothing was said about who designed the P/F, I gifted that to Sig but told them to copy my plan as close as possible, they did pretty well on that but there were some changes to the parts for production. As it turned out it flew pretty darn good even though it was heavier than the kit version.
Over the years I’ve had the great honor to meet many people that have become life long friends, some are gone now and will be missed, but many others are still kicking, thank God for that.
Later,
Mikey
