I am struggling with trying to identify this CD 133. It has no embossing. I don't believe it to the either of the listed Canadian pieces as it does not have MLOB and the dome does not match the 'tall narrow dome' style. Based on the color (either a celery or yellow green), that leaves me with either what is listed as the DEC 19, 1871 Patent Style or just the Noe Embossing MLOD/SB style. I am not familiar with the DEC 19 style. Can anyone out there provide any assistance? Thanks! I received several emails on this (thanks to all) that informed me that this is indeed a Canadian 133. I guess that not all the [010] pieces listed in the PG have the tall, narrow dome style. Thanks again for the replies for help.
