Job lot of 3 old razors bought for $50. Cheap enough or not I don't know, but its done now.
Narrowed down the ball-end to maybe around the twenties thereabouts, but I need the experts here to help out with a definitive id. I wasn't able to see
"an identical" example in the pics on mr razor's website (thanks
@Mark1966 for that resource link recently), but it did help me narrow it down somewhat to maybe an old type, new improved old type, maybe even a brownie, I dunno

¯\_(ツ)_/¯ . more reading about the Canadians on B&B, but that didn't give closure either.
Don't know if being a Canadian makes it more difficult, but it is what it is. I'm just glad it survived around 100 years in this condition. No serial number, no cracked handle, plating appears all there, comb teeth are all straight and in tact, no plating loss, thread stem in head not cracking away from the head from overtightening. Just really tidy.
Cleaned them all with detergent & bi carb mixture in the ultrasonic bath, and just a quick rub on the oldest one with PlasticX to clean up the shine afterwards, and it is gleaming! So much so it looks hardly used.
There is a mint condition sealed blue (new improved) blade packet that might indicate age/id, if it is correct original supplied though of course. A lot can happen in 100 years with mix n match, even from the factory according to what I've read.
It looks like it might have only been used a few times (4 blades worth of shaving maybe?) and then just displayed for decades with the lid open. The faded purple velvet in the lid makes me think this.
So have at it guys, enjoy the pics, and what is it?
Oh and there are 2 others, aluminium handle, one looked like it wanted to give me tetanus

, probably only decoration now that one now it's cleaned up.
Corrosion and dent (peeled plating) in the edge of the head relegating it to the cheap seats. Handle is ok though.
