Ashley:
There is a company that puts out some nice 1/32nd resin kits of various Pitts models. The name of the compamy is Airshow Models, and there web site is here : http://www.airshowmodels.com/.
One of the kits they presently have available is in fact an S-2B.
The site has a discussion forum, and perhaps someone there can point you in the right direction.
