Ross Rifle Sight #2

I am not familiar with this BSA sight, but do not believe it belongs on the bridge in the photo. The receiver bridge fits the Ross Mk II and, in my opinion, is the milled version most frequently encountered. The sight does not have an aperture, and would be difficult to use when mounted so close to the eye. This target sight would be more appropriately mounted on the barrel, and would fit some models of Ross Mk II and several pre No. 1 British service rifles.

There's a fixed hole just below the lower "V". I've have to measure with a guage pin to confirm size. Looks like it belongs on the base. I don't see any modification to fit it. Would be much wider if it was going to be barrel mounted on an Enfield. I can measure both if anybody interested.
Actually, the Ross bridge mounts and the pre No. 1 British barrel mounts accept the same sight base. I believe it is referred to as an "Enfield Standard" base, but may be mistaken in terminology. It goes right back to the Snider and, I believe, the Enfield percussion. I will post a pic of the aperture, if you pass it along.
Hi rgg. The sight base is for the Ross Mk II** military target rifle. The sight, originally designed for the Lee Enfield (Long Lee of course)is patented 1908 I believe but the slide has a patent date of 1907 on the back. Your sight is missing the right hand securing screw and the locking lever and spring (identical to the left side) that secures the slide in place on the long elevation screws on both sides. V notch rear equals barleycorn fore is the sight rule. It was not a cheap sight for the pre WW1 years. Common to find all sorts of sights designed for the Enfield on the Ross. I have one of these sights in mint condition. Remember that this sight is graduated for the Mk II/VI round tragectory. Pop around someday for a boo at my trash.
Pre No. 1 from left to right:
Martini Henry 0.282"
Lee Metford Cavalry Carbine 0.285"
MLE (Long Lee) 0.284"
Ross Mk III 0.289" (H.W.Cooey sight)
Ross Mk II 0.286" (Canada Tool military version)
The No. 1 has an entirely different sighting system.

Receiver bridges are, without a doubt, encountered on the Mk II** more frequently than on other models of the 1905/Mk II. That said, I think one would be mistaken to consider it an item exclusive to the Mk II**. A bridge was a factory option and bridges, including this one, were also available in the after market. They could be, and were, fitted to other models of the Mk II and 1905. It is more correctly referred to as a bridge for the Mk II and 1905 Ross.
MLE Competition sight.
This sight was intended for use on the MLE series of rifles.
It was approved for competition use. I have a pamphlet on it buried inside the cover of one my books, I'll try to find and post.
As you can see, there are two zeroing lines on the slider. One marked V for the V notch and one marked O for the aperture.
Pressing on both sides of the slider releases it so can be moved to set the range. Fine adjustment is done with the top knob.
The sight is well made with the precision of a clock mechanism, adjusting with the knob with the little gears in there feels similar to winding a watch.
Left scale is used with the sight folded down for up to 200 yards+. The right scale is for use with the sight flipped up for long range.

Englishman - that's great info. If you can find the pamphlet and post that would be greatly appreciated. Certainly an interest sight. The chap's estate that I got this from 12 or so years ago was a competitive shooter.
