The explanation for the missing front sight goes like this: The article was researched by observation---Neal's, and more than a few helpers. Bottom Line on this laborious task is the factory kept no records on sights---save for three which were patented---and only one of those was ever used.

Observation translates to if any given sight was not observed on a gun, there is no mention of it in the article. It was believed all the missing sights were fronts---right up until I stumbled upon the "Large Screw Spring Up" rear some 20 odd years ago.

So here we are, believing there are other sights, such as the one here-----but we don't KNOW it until someone tells us about it----so keep looking!
