Has anyone seen a numbered Canadian Pacific? This looks like a 143 [100]. The rear skirt is embossed "STANDARD". There is what appears to be a "1" strongly embossed over the "A" in Pacific. Is the "1" a strong remnant of a blot out or is it a number?

This mark is most likely either a chunk of unmelted scrap glass embedded in the surface just above the A or it could be the remains of a blotout. Thank you Barrett.
