Help Identifying Lyman sight and Globe sight

djsmith4 · February 7, 2014, 02:08 PM

I have 2 sights I need help identifying what model or rifle they fit. I know that one is a tang sight and the other is a globe sight but that's the extent of what I know. I would appreciate any insight.

Looks like someone mounted a level on the wrong end

Welcome to TFL !

If you measure the center-to-center distance of the tang sight's base mounting holes, the manufacturer's customer service dept should be able to determine what gun(s) it fits.

The globe sight would fit just about any target rifle with a target front sight mounting base.

That globe's odd, though - The knurled aperture holder is normally toward the shooter's eye when the sight''s mounted to the rifle.

So should the level, so the rifle's plumb/level hold can be readily-seen while aiming the rifle.

That sight with a spirit level is one designed by a National High Power Rifle champion back in the 1960's. I've used them for decades. It's mounted on a band clamped on the muzzle with a dovetail base screwed on it as shown in the left hand picture. With another level on the rear sight windage arm and leveled, the front band is twisted so it's also level. Different size apertures are used with hole diameters from .075" to .125". Then when the shooter looks through it, here's the sight picture seen on bullseye targets on the right:

With the rear sight level, there'll be no windage zero change from short to long range as it moves up and down for different range settings.

Leveling the rifle for each shot eliminates wide shots at longer ranges due to how much the rifle's canted to the side.

Here's some sights used in the late 1800's:

Note windage adjustments are on some front sights.

Bart B,

Thank you for your help. You are definitely a man who knows guns.

Petah, that globe front sight design is based on Redfield's Big Bore front sight pictured here:

It's designer also had levels made to attach on the Big Bore's side but look the same through the rear sight. It has a cap on the front that unscrews so apertures can be changed. With the level at the back, it's easier to see in rapid fire matches.

With a few calculations, the rifle can be canted a bit to move the bubble a given amount to move bullet impact left or right a half or a full MOA at long range. Shooting under a coach reading the wind giving a "half right" sight correction, the shooter cants the rifle right, watches the bubble move half it's width left then says "half right" so the coach knows he made it. Then fires the shot after making a correction without having to go out of position, twist the rear sights windage knob, go back into his shooting position then fire the shot.
