All About Pocket Knives

Hey guys been gone quite awhile due to health. I found several TL threads pertaining to this but didn’t want to wake em up. Here’s pics. Ulster Knife Co.
I’ve been told by more than one this is possibly a ww1 copy.

It’s shorter, also shorter bolster. But I’ve also read the screwdriver blade would have two notches? Any help would be appreciated.
Due to health I’ve been selling off a ton. Getting toward the end of militaries.

Oh. About 3.55 closed and bolster about 1/2” on the sides.

Thanks in advance.

If it has the liner lock and no brass would bet it’s WW2Era.
Here’s a pic from Mr. Silveys book .

Thanks Rip. I’m just seeing this. Never got the email notification so I’d better check my spam folder.
Yes sir it has the liner lock for the screwdriver blade and no brass.
I can’t believe I didn’t but I’ll post a pic of front and rear view in a little while.
