Nice earlier SDP Hemingray toll telephone insulator in a dark teally blue aqua. This insulator has a large weird looking dome embossing that looks strikingly like a boat anchor and a nice sized bubble in the skirt. I would suspect that this is a large #1 that the mould got messed up on. Anyhow, just kinda different from all the other boring Hemi 16's out there. VVNM cond and great dark colour too.
