Sidearms & Scatterguns Buck Knife with no Model Number

[DirtyDave]

Got this Buck knife that doesnt have a model #. Closest thing I found was the Buck 119. I like the shape of the 119 better than this one so I'm going to re-shape the blade. Blade is 6" and its 10-1/4" overall



Want to shape it about like this

What is stamped into the blade?

I've read the following from other sources and was thinking this would be a good place to either have it confirmed or corrected.

early Buck knives made up to 1968 were marked on the reverse side only with the name (Buck)
1968-1972 knives were marked (Buck, USA) two lines.
1973-1981 knives were marked (Buck, the knifes model #,USA) three lines.
1982 to present marks were added to the knife to indicate the specific year of manufacture as per this thread.

I've heard all kinds of different stories on when Buck knives where marked with what. The above seems to be the most consistant story but it would be nice to be sure.
