Ran across this CD 145 Brookfield  while rearranging the shop. The light aqua insulator is nothing special but I don't recall seeing a shop number like this before. It is a large backward 06 with a much smaller right-ways 6 carved into the "O" of the larger 6. Is this known? Maybe it's a back east thing and not seen in Montana. If any CREBHeads have seen this please sing out. I'd like to know if this bit of poetic license by the mold maker/engraver was common. Thanks.
