Here is an early photo of the insulator collecting Colburn brothers circa 1971. Left to right: Jim, Jerry, Alan, neighbor kid, and Paul. Note the wonderful 'el-cheapo' type insulators that we had found or purchased in the Lake Worth, FL area. I am holding two standard porcelain 3 " rack spools. Real valuable even now! We picked up any and all glass and porcelain insulators that we encountered back then. Enjoy!
