Ok, here's my Recon Scout and Kukri.
First is my Recon Scout. I bought it on eBay for $61.76 with shipping.
As you can see from both sides, it is both sterile and without a finish.
Here's a spine shot
Here you can see the 2nd marks on both sides of the guard and the butt.
And here's my Gurkha Kukri that I got on eBay for $53.85 with shipping.
I don't know if this is a factory sheath. I've not seen another one like it.
As you can see from the handle, the previous owner worked it pretty hard.
And here they are with some of my Rats.
