Porcelain Insulators from Mexico

Similar to the US, Mexico used a wide variety of both glass and porcelain insulators.  They share standards with the US and therefore share many styles along with the standard one inch pinhole.  For glass all North American pintypes share the same numbering system, for porcelain they are separate.  The porcelain insulators are identified by U-numbers, but in the range of 1000-3999.  The link below is for the reference book that covers these insulators.
