Thank you for the reply....Great history!Its been fun watching everyone grasping at straws. This sling is a close clone of the Marine Corps 1907 sling using my Grand Fathers(USMC ret.) recycled frogs, it was strapped up by Les Tam. There are many details that are purposely omitted from a original Marine 1907 sling, just because I didn't want to be accused of faking a original sling.
The leather is very thick and stiff but it is wearing in nicely, no secret sauce used here. And being a much larger person than the last generation was, the main strap is 56in long.
Interesting connection between Les Tam/Ron Brown that makes their products similar.....both are great humans.
Old school USMC 1907 slings used an odd pattern for the strap holes.....did you replicate that? That leather would never be mistaken for "issue". Gunny Turner thinks the origin might have been a saddle maker in Southern CA and a "small" USMC specific order.
