In order of coolness, from left to right: Anderson, Posa Fuel, Holy Pegs, and H-D. Does anybody know anything about Anderson or it's history?

Note the markings. Holy Pegs (no name). Harley's are marked H-D on tip and Made in Taiwan (boo!) inside. The Anderson's are aluminum, not sure on the center two. H-D's are heavy pot metal.
The steel mount for the Anderson above is incorrect. The threads in the original aluminum mounts tended to strip. I have two sets and both have the mounts replaced with steel units. I have saved some original aluminum ones but they need repair.
The Posa peg and the Holy peg were mismatched in a box of parts I recently bought. I have since found another Holy Peg so, now I'll look for a Posa. Posa Fuel and Lake made those (injector) slider carburetors in the 70's. I don't know who made the Holy Pegs, Custom Chrome sold and may still sell them.
Harley still sells the ones on the far right with clamps (H-D #49144-86), as a multi-fit item for engine guards/crash bars.

Unknown NOS stamped steel pegs and mounts. I once had (sold), two of these sets. One set had a flat instead of rounded tip. They have very subtle round bumps on them.
This is just a small sample of the different styles and brands out there. I've seen some very similar to Anderson but marked ETB?
