If I've correctly identifed the dot in the upper margin, it looks to me more like a stain (pre- or post-production) similar to the mark in the bottom right margin.
I don't think that the Unitrade Catalogue will lists these simply because they are inconsistant varieties or more of a 'flyspeck' type (?)
Blackjag has already explained the 'dot' on the Baldwin stamp but the harvester stamp has a variety called 'ink splatters' and, again, this is just a flyspeck type and will not be listed in future editions of any catalogue as far as I know.
The varieties have to be 'constant' to be added as a plate variety and even all of those are not listed in the catalogues anyway. :(
You are doing a great job with the miniscule varieties. Ithink you are making people pay more attention to their stamps and recognize the detail. Thank you and keep up the good work.
If you don't have a copy, I suggest that you obtain a copy of CANADA: STEEL ENGRAVED CONSTANT PLATE VARIETIES by Hans Reiche. The book was published by Unitrade Press in 1982 but copies still seem to be readily available. This is a worthwhile addition to the library of any variety seeker.
By the way, neither of your items illustrated above is included in the book as neither is "constant" or identified as to plate position.
