During WW2, whilst in the Halmahera Islands, my grandfather acquired an M1910 eating knife, and I thought I'd look into the history of them.

Part of the story is easy, Its an American Cutlery Corp M1910 made in 1918. What I can't get any information is about the stamping on the other side of the knife.

It's pretty basic, but is is; A A 105 13

The spacing is deliberate and roughly to scale.

I know it's a long shot, but does anyone have any way of deciphering it?

thanks!
