Wally,
Although of much more recent production, this nice #11-4" was built out of old canvas micarta. It has been called several names in the past:
A) Bees wax
B) Honeycomb
It is very way-cool old material. As many of you know...I gotta' lot of handle material, aquired over 4 decades (or so). I have a few more examples of this stuff, which I plan on making up.
Here's a couple of photos...
Best, Capt. Chris
