Canada Post Card Help

I've been trying to ID some stamps on my own and have had some success however I've come to a bit of an obstacle on these Canada Post cards.
The first one I believe is a UX33 but I'm not sure if it's UX33 d, e, f or k?
Top line is 82 mm long ( Canada Post CARD)
Second line is 72mm long (The Address To B.....).
Stamp is 18mm X 22 mm.
The second card I believes is an UX66-d because the inscription Canada Post CARD is 81.5 mm long.
The stamp is 20mm X 24 mm.
Confirmation on if my assessment is correct on this one please?
Any and all aid on these would be greatly appreciated.

Cheers, Bill

Hounddog!
I use Webb's Stationery Catalogue to Identify my items. There is a new edition coming out soon and it will be the Bible of Canadian stationery.
From the 7th Edition, for the first item: 2¢ Admiral carmine:
It's Die II typographed, Type 6 (2 lines).
So, if it is NOT on thick soft stock (P33g), then it is P33f.
That would make it UX33e in the Unitrade catalogue.

I'll have a look at the second one later.

and...
the second one: Geo VI 1¢ green
It's Typographed, type 5, not mimeo'd, not rouletted.
So, it's P66d or UX66c.
Hope this helps.

Sak, I truly appreciate you taking the time to reply.
Knowing the answer I follow it completely how to get their now.
The UX33-k reads Type 6 1917 Confederation, English.
Do you know the difference in this one?
For the second one I can read 19 38 in the bottom corners so that would mean Typographed.
The UX66-d is offset and has 19 43 in the corners.
so that makes this UX66-c.
Thanks again!!

Cheers, Bill

Just noticed your reply...
"Confederation" seems to be a variety (P33l and P33m) that has a large printed square table of data on it. I've never seen one.
Stay tuned for the new Webb's. It's worth every penny.
It's a pleasure to help out.
