Please Help Identify Sight Ladder

Please Help Identify this Sight Ladder. Seems to be high quality and marked for out to 2600 yards. Also on edge has graduations for MILS to 60. THANKS! Salt Flat

Sure looks like the back sight off of a Lee Enfield to me. Have one like it off of one that i had scoped only don't think it has mils on it.

Looks to be one of the rear ladders off of a USGI support weapon from WW1 / WW2 / Korea time frame . These were found on BARs , 1919A4s , 1919A6s , and .50 cal BMGs . They are not interchangable , but they are all close to each other . Is there any marking along the top bar like M1 ( 30 cal M1 ball ) , M2 ( .30 cal M2 ball ) or maker's marks ( sg , ba, w ,c in a box , etc.) ?

Mausernut, I compared it to a couple Lee Enfield sights --at first glance it is similar but is really quite different. also much heavier and higher quality.

Chris, I did find a C in a box on the elevation knob. The sight is very solid and it seems logical that it could come from one of these more heavy duty arms.

THANKS! Salt Flat

I don't think it's the 1919A4, they only went to 2400...and had an open battle sight. The .50 goes to 2600 yds though...I'd say that's what it is.

Jim, That makes complete sense. I couldn't think of anything in the rifle realm that would be calibrated for that distance. Thanks Salt Flat

Only the Browning 50 cal has the leaf with the peep sight, the M1918A2 and 1919 BMG's all have a open V notch on the leaf when folded

1918 BAR wouldn't be graduated for as far either. 1500 yds I think?

Checked my slides last night. It is more complex than stated above as the markings changed over time due to ammo specs and meters vs yards . However , RCS is correct , only the .50 has the peep on the close range sight. Three of my four have ranges to 2600 , the forth going to 2400 ( it's in meters ) . All four have mils going to 60 ( plus two tics ) . A C-in-a-box means Colt production.

Emmagee1917, Yes, has the peep, the MILS 60 plus 2 tiks and the C in the box. What really impressed me about the sight is the heavy duty quality and nice parkerizing. It makes sense though being a Brownning design and Colt manufacture. Great forum-- I don't know where else I could have found this info so fast. What is funny is that I have had this sight in a box of old parts for about 40 years and never knew what it was. Thanks to all! Salt Flat
