Shown are two CD 106 Ericssons that a friend brought back from Mexico while visiting her family. I asked her to be on the look out for glass insulators, so she went to her town's telephone company and they gave her these little insulators. The first is in script: Cia. Comercial with Ericsson S.A. underneath. The second is amber swirled / two toned with ERICSSON in front and TELEFONOS on the back.
