Peter J Michels Spear No 10

Hello
"Peter J Michels Spear No 10" Had it for a while now, I've been looking on/off but cant find any info on the Spear razors. I have seen No 12 and No 11 but never a 10.

Not sure what the scales are made of. Straight, but faded. Has inlay both sides, both ends. The outside end has some green/black inlay, other side is just text. Blade is flat ground and in great shape. Just needs polished and honed. The pics suck

Is this square point or rounded or slightly rounded?
Has anyone seen this razor before?
Are there other spears No 0/1- No 12?
Any more info on Spears or Cmons or PJM?

PJM operated between 1914 - 1955. The popular Cmons were from around 1920s on. So are spears pre 1920s? And since PJM was mainly a distributor for Cmon does that mean that spears were made by Carl Monkhouse or by someone else?

Here is some additional info I gathered on forums:
