Offered here is a CD 190/191 diamond Canada 2 piece tramp insulator. Deep royal purple and V NM, there is a tiny flake type chip on the dome WG lip edge and 2 tiny flakelets on the top piece base edge. I have also noticed that both the top and bottom bases appear somewhat uneven in places. These areas look like they were polished but are NOT resin repaired places. The uneven places are solid glass and I thought I should mention this for accuracy. Very clean! Was asking $150. NOW asking TRADED + shipping.
