A couple of observations:
1. your slide is not really early, the front dust cover and the front sight block are the standard length, and it appears to have mid point roll stamped markings.
2. your safety is a Mk2 Inglis - I've only seen 1 in person - my understanding is that they were a post war, probably CAL produced item, rather than Inglis production.
3. your frame doesn't appear to be slotted for the shoulder stock? if it is not, it is a guarantee that the frame and slide are miss matched.
4. There were un-numbered frames and slides available thru the Canadian system (into the late '60s at least). All the Frames I'm aware of were Inglis manufactured, We've seen Inglis & CAL manufactured slides.
- as stated, the pantograph engraving is sometimes very shallow - it could have been "wiped" by sandblasting the frame for re finishing.
5. There have been several photos of similar Cyrilic marked slides (it seems now that they were they of the same one?? gunboards post several years ago SU002x) - but so far as I'm aware there is no documentation on them. I suspect it could be an experimental follow on to the Chinese marked slides, and a precursor to the Mutual Aid Board decal (except the MAB decal was authorized in mid 1943 - ie. before Inglis was in production of the BHP).
Is the gun a deac? lots of deacs have been "re-marked" with spurious and fantasy markings to increase their "value"
The thing that disturbs me about the KAHADAH marking is the width of the cutter, and depth of cut (I think that they are too wide and too deep). If you look at the Chinese marked slides, there is a delicacy and verve to them - they used native speakers to produce the script -
an observation in the Gunboards threadhttps://forums.gunboards.com/showthr...nglis-Hi-Power is that the word "Canada" while spelled correctly is all lower case - There were plenty of first generation Russian
speaking immigrants in Canada during the WW2 years, I cannot believe that they would not capitalize the spelling of the name of their new country (remember, many of them legally no other home than Canada as they had been dispossessed of property and State - White Russians and various other no longer existing provinces of various Empires).
