I don’t think this is a Jabo.
l lean alley because the glass doesn’t look clean enough for CAC, but would like to see some other opinions. Although the size at 21/32 could be CAC. Tough one!
Thanks for the extra pictures. I don’t think I would put this in the Furnace Swirl Box but probably need to see in hand. Maybe just a champion? Nice MiB either way!
