SMLE Oddball Sniper?

I don't believe that scope mount set-up is all that bad. I've seen far worse sold on the commercial market. The forward jacking screw and (hopefully) a reasonably tight fitting cross pin would do most of the required locating. However, the single rear screw WOULD require a good installation job.

Is it "military" grade? No. But neither is the scope! (Of course, mounting an A5 on the side of the rear sight protector and receiver AND then putting it in the trenches seems a bit mad at this late date, too.)

If you want to see some really scary mounts, see Brophy's '03 Springfield book. Frankford Arsenal test stuff included. Oy!

It would appear that the single rear screw that sits on top of the barrel isn't fixed to the barrel in any way JM. It is to a) give a degree of lift at the rear in order to impart some spring tension to the backsight bed spring and b) maybe allow the graticle to be set a bit centrally prior to zeroing. But how you'd do 'b' with the sight fitted is anyones guess. From what I can gather, the rear screw isn't fixed in any way to the knox form, it's just sat on top of it, ready to whip the bar and sight.

The trouble with the setup without a rear suppoost is even a .001" degree of play on the mount and axis pin, whether up/down or left/right is that this play (very simplified of course) becomes multiplied/increased by the length if the bar at the ocular lens and multiplied by XYZ at the target.

I hear what ou're saying about the dire quality of some of the earlier SMLE sniper mounts,but at least there was a degree of inbuilt strength. Anyway, we've established that this mount is an inter war commercial expensive fix. And good of them to try - albeit not a GOOD try!

Again, another example of "Buy the rifle-not the story."

At any of the Gun Shows where I have taken a table and offered items for sale, I have always stuck to one principle, and that is ' answer any questions as truthfully as you can'.

When asked about a rifle or item, I only restate what I know or was told about that particular one. The follow up question by the prospective buyer is usually on the lines of "Are you telling the truth?"

My answer to that is "Yes, because I am lazy!" Which gives a surprised look.

I qualify that by telling the person that if I tell them what I know about the item, then three years later when they come back and ask about it, I don't have to try to remember what I had told them.

And, just passing the 70 mark, I find that it is getting more difficult each month to remember a lot of stuff.:lol:
.

Couldn't agree more. Of the VERY few original SMLE/WA5 mounted snipers I've seen, all were fitted with the typical Whitehead Brothers offset mounts as per Badger's photo's of good lady's rifle! I very much doubt the over bore rails were ever adopted for sniping use.

Many thanks to all who have taken the trouble to read and comment on this thread. The information given to me at the time of the sale was "honest" in the sense that this is what the seller had been told he did not pretend that it was true only that it was what he had been told. I paid what I considered to be a reasonable price for the rifle and bought it because it was "different" not because it may or may not be worth a lot of money. I have yet to get the rifle onto the range but when I do I will post my findings on the mounting systems performance, either way I have a rifle in my collection that will talked about for some time and one that I hope will give me hours of fun.
The one thing that does trouble me though is if the mount is a copy of an origional Parker Hale item why bother to engrave it with BSA and a serial number or did BSA actually make copies themselves????

Somewhere I've got some photos I took some years of one of these mounts on a rifle belonging to Adrian Dagger. I did upload them to a hosting site, which folded some years ago taking them with it. Must find the prints.

This, on the other hand, is entirely made up, quite recently, by a talented retired engineering worker who brought it up yesterday. The Aldis sights were available as parts from the trade into at least the 1950s.

The trouble with the setup without a rear support is even a .001" degree of play on the mount and axis pin, whether up/down or left/right is that this play (very simplified of course) becomes multiplied/increased by the length if the bar at the ocular lens and multiplied by XYZ at the target.

Ach, yes, missed the obvious there! Never mind...

Interesting photo that; looks vaguely familiar! :D

Not much of a system, but then the Winchester A5 was not much of a scope! Still, not much worse than the Whitehead pattern that attached to the backsight protector; a part that is not known for the rigidity of its fixing, and to the stock no less. ;)

If they had put a spring steel strap around the Nock's Form and tightened it up with a screw, rather like those WWII German scope rings, they would have been onto something. And with a fine opposing windage adjustment screws on each side of the backsight base instead of just a pin going through, it would have been quite useable by the standards of the time, and could have actually been collimated after fitting with just a screwdriver, as the screws at either end would have allowed for vertical adjustment as the others would for horizontal. Such is hindsight. Would have been rather prone to bend in the vertical plane though.

Come to think of it, they could have put the rear foot right on the receiver ring and avoided the taper of the Nock's Form. Would have meant relieving the wood slightly where the spring wouldn't follow the concave shape under the body, and putting a hole in the spring for the forward guard screw projection, but probably could have been done.

Hi I have some information on your scop mount if you require it.

I borrowed Adrian Dagger's original Parker Hale mount and had half a dozen copies made, Adrian having his original back plus one copy. The one in the thread has machining marks just like the ones I had made. Therefore I think the BSA marks are fake and added in the last few years. Adrian seemed to be able to get some reasonable scores with his set up. These mounts were always designed to be paired up with the Winchester scopes. The way the scope slides in the mount probably considerably lessons the forces acting on the rail so may help to make the whole set up work more effectively. If you read Parker Hale's advert carefully they seem to claim they they designed this during WW1 - I can only guess that would be for a military application.
