I’ve seen a Perjeco catalog (note that name is the cable address), but not a Perfect Jeep catalog. I’m not sure how those two companies are related (or maybe one is just a DBA). The catalog is probably not worth much.

Not to far away from Berg’s King of Jeeps. A guy could make a day of it and hit J.C. Whitney and downtown for pizza. I have been to Berg’s and J.C. Whitney, but never new about Perjeco at that time.
