On the right is a regular CD 133.2 No Embossing – Canada EIN [010] [No embossing] {Slope shoulder} {Comes with and without small button on dome} {MLOD} SB. This one has the dome button, and is shown for comparison. On the left is the unit in question. It's also a CD 133.2 EIN [010] with the dome button, but this one obviously has a substantially taller skirt than the other. (It's bluer too, in hand, with a nice olive streak; too bad for the base bruising and circumferential dome fracture.) Of the relatively few CD 133.2's I've seen, either in person or in photos on this site, they all seem to have the shorter skirt. My first question is how common is this size differential for this CD/EIN? And second, does it matter to the CD 133.2 specialist? Thanks for any insight.
