This tough CD was made to Fred M. Locke and John Lapp patent for a rams-horn insulator that would mount hanging down from a cross-arm (US Patent 402,752). Brookfield was most likely the manufacturer. This has since been moved to CD 1182 as it is technically not a pin type insulator. Photo courtesy John & Carol McDougald.
