A friend of mine came across what apaers to be an old hand made hunting knive with Summer stamped in as a logo.

Looks like stainless, hollow ground, 3/16" x 4" blade, ebony or horn spacer with sambar handle and brass gaurd. The fit is good, but the blade is over buffed and the details washed out somewhat. It also has a finger notch ground in front of the gaurd and ricasso.

The only other marking appears to be with an engraveing tool,"710107"

Any ideas?
