Here are five round base CD 145 B [037] insulators, all in different shades. Going L to R.

Dark Olive Green...good condition

Dark Yellow Green....good condition ..real glower

Olive Amber(strong tiger striped)...frost pop dome, one sliver of glass missing

Brown Amber (strong tiger striped)....frost popped right inside wire groove. Perfect match

Brown Amber ( dark red stripe)... has couple short cracks on base but not bad at all.

Selling as a group. $400us and I will pay for shipping within Canada and the continental USA.
