The "arms" on this "Y" embossed Pink CD 129 glass insulator from Chile seem to be located in different positions on different molds. This close up reveals the basic structure to the embossing is a "Y" with a base or underline to it (as you may have seen in glass stemware symbols). Some believe this could be a way of dating production. I'm leaning towards that conclusion myself. The basic structure to this embossing reminds me of a symbol found on a CRISA insulator made in Mexico [id=157071231]. I'll post another insulator photo from Chile that more clearly shows the base skirt embossing [id=].
