I've had some house renovations going on, which my other half insists is more important than the hand-guard, so I couldn't get to it as soon as I wanted.  I finally got to it today, and managed to get a fairly close match on the finish - much closer than the hand-guard that came off.

[Edit/Add] I thought about trying log-wood just to be 'authentic' but decided to take the easy way out.  A few of the stains that I wanted to try were out of stock/no longer available.  I wound up using 'Military Stock Stain' (with a hint of red) from Chestnut Ridge Supply. I will continue feeding it Flaxseed oil until it stops taking it.
