This is another Stebbins patent. The patent info can be found at this earlier photo of a Stebbins LRI [id=207429258] These LRIs are embossed: Patent//Pending .The aqua color contrasts well with the olive green streaks. The bracket shown is not confirmed to be from a Stebbins LRI. I do own one proper, original Stebbins bracket, and it looks like most others of this style! Acquired in a trade with a New England collector in August 1995.
