All About Pocket Knives

I may have posted this question at one point but does anyone know details on this stag handled switch and approximate value?

Blade seems tight in frame. Snaps open but not into place all the time. I oil it and move the blade back and forth lightly a few times then it works for a while then it seems like it tightens up again.

edit - just shy of 4" closed

I can't find where I might have posted before. Old Timer's disease I think.

Very nice 1960s folding guard knife!

Thanks Bill. Any idea on manufacturer or were there a large number of Italian manufacturer's that made these types of knives?

Sorry, I don't know who made it.

Thanks Bill. Thinking about listing it for sale in for sale section.
