Here's a newly discovered Ice Green glass radio antenna strain insulator embossed with "SB". Manufacturer is Santos Barosa Vidrios, S.A.- a Portuguese company that was recently purchased by a Spanish company Vidrala. Has internal crack on one eyelet with some light milk wisps that follow the crack which leads me to conclude this was a factory flaw. Factory grind mark on opposite end with some light surface roughness from usage. Measures 3 5/8" from end to end. Approx 3 1/8" (using hanging method).

First email gets this rare radio strain for the final reduced price of $60 postpaid. Thanks!
