Possible Early Holley Knife?

[paleomaxx]

I found this pocket knife today in a 1780's to 1880's field. After a little cleaning I'm fairly sure the first word on the brass plate is "Holley" and the last is "Co." Not sure on the middle. Does anyone recognize the diamond with dots in the center design and know the rough date range?



Both sides are identical and there are three pins holding it together.

Looks like a variant of this one from late WWII
