From the photos it looks like there no markings on either the grip or cross guard, can you confirm if there are any stamps? Good looking knife, very clean.
No there are no marks on the cross guard or the grip.
I was hoping there was a number on the grip 1-4 but none are present.
The plating is of very high quality and I wondered weather this might have obscured any marks.
The pommel nut definately looks like a WW2 one..........but the shamfering of the handle near the nut looks unfamiliar.
A bit of an ennigma
Thanks and regards

Your knife has a pommel matching the middle example in the photo
As you mentioned, according to reference there were 1 to 4 markings on the handle presumably from each of the 4 makers of the handle although apparently there were numerous makers of the blades and finishing on the 3rd pattern
I'm sure you've had a good look on the internet at some of the collector sites, there's a lot of info about all aspects of the knife.
