I have only seen ONE Hi Power with the maple leaf decal, Fellow brought it into the local gun store and took it out of the ORIGINAL box!
Just an add, have three, one of each variation.
Technically there are @5 manufactured varients and 1 "constructed" varient?
No1MkI ~ Tangent sight, early round barrel cam, low ejector, early extractor & hammer
No2/1MkI (my own terminology)~ Early fixed sight slide on slotted No1 frame, early round barrel cam, low ejector, early extractor & hammer
No2MkI ~ as above with no slot in frame
No1Mk1* ~ Tangent sight, rectangle barrel cam, high ejector, later internal extractor & Mk II hammer
No2Mk1* ~ Fixed sight, rectangle barrel cam, high ejector, later internal extractor & Mk II hammer
No1 upgraded to No2 status ~ a new No2 slide put onto a No1 slotted frame, or a No1 slide modified to No2 status by milling the tangent sight off and pinning (British method) or silver soldering (Canadian method) the No2 rear sight block to the slide.
