Here's a tough pony glass insulator from Argentina. Its only embossing is Industria Argentina! These were made by Cristalerias Rigolleau originally and can be found with their logo "CR" but strangely this piece doesn't have their embossing. Much tougher pony to find than the more commonly seen Vidrart marked insulators.

This rarely offered insulator in VNM shape can be added to your collection if you are the first person to email me for only $45 plus shipping. Thanks Bob
