I bought a used sidelock mainly because I thought the sight was cool.



It appears that you can use it flat for close shots:



Or, flip it up, " Quigley Style " for longer shots:



It has a custom, high rise front blade mounted on the 1/32 twist barrel. Anyone familiar with the make of this sight?

it looks like a vernier tang sight.

It may be a Vernirer but it's designed to sit on atop octagon barrel.

almost looks like a "Frankenstine" sight made from a Lyman vernier and a williams Peep?

Whatever it is, it's cool. It it weren't for the octagon barrel issue I would have guessed it came from a European battle rifle modified for sniper duty.

I've done some searching around the net and have yet to see anything like it.

That front lever swings to the side and to allow you to adjust the rear for windage. While a little old, it's built very solid. I may be customized from some military rifle but it sits perfect on the barrel?

FYI for an update.

It's from a 1901 Krag Carbine. It's been modified with a Williams aperture. The gun was the workhorse in the Spanish / American War. The sight appears to be original equipment. I'm impressed with the craftsmanship of the era and it's cool to shooting with a sight well over 100 years old. I may have to try some long range stuff with this rifle.

I'm currently reading " Sharpshooting in the Civil War " and becoming inspired to stretch my distance.
