Ross M-10 rear sight question/problem

[rayg]

Thank you Tom, that photo explained it all. How did did you get the plate off if the drums won't turn it off? And is that what the part is called so I can look it up and order it from Numrich, Ray

I do see mine is cocked there, I will try to fix that, Ray

Ray, My rifle was one of those that found its way to India and was not well maintained or in a humid environment, or both. I was able to defeat the rust with a week of soaking in Kroil. However the very fine threads on the drum were damaged by the rust to the extent that the windage plate would move without my intent, (on recoil or a bump etc.) Numrich does not offer the small parts separately, just the complete sight in 'good' to 'very good' condition. The one I received was excellent. I'm not sure how allignment with the elevation screw has any effect on the windage adjustment as the windage assembly is integral to itself (picture) and its operation (or lack thereof) is independent of the rest of the sights operation.

Success gentlemen! Got the drum to move the plate. The drum will not finger turn but needs to be helped but was able to move it right and left. Thanks everyone for all the help and suggestions, Ray

Well still problems with moving the sight. It will only go so far to the right and stops and still shoots left. Looking closely I can see the sight must have been hit or banged as it is slightly cocked as muffet mentioned. That must be the reason it is binding up. I ordered a whole sight assembly from Numich Arms for only a little over $33.00 as oldpaul suggested. I hope when it comes it's also in decent shape, Ray

The crossed-flags-DCP making was applied by Canadian military inspectors, who had a small building right at the Ross Rifle Company factory.

The DCP proofing standard was identical to that used by the British military and the DCP mark was accepted as the equal of the BNP or GP marking on a British-made rifle.

There was a very great effort made at that time to have a single standard for Imperial/Commonwealth usage in many areas; rifle proofing was just one of them. Another idea from the same time frame was Imperial Penny Postage: 1 penny or 2 cents would carry a letter anywhere on the map which was printed in red.

We seem to have lost a great amount of that in recent years. Today, our "best friends" seem to be China and Japan, never mind that they both hate our guts and are trying to destroy our economy.

Politics!

I prefer Cats for company, Firearms for logic: something you won't find much of in 'international affairs', despite all the smiling, promising and posturing.

Best way to clean these sights or any that are not easily disassembled is in an ultrasonic cleaner. Gets everything out of all the pockets and recesses, except rust of course, unless you use vinegar, which has to done after you get all the grease and oily dirt off anyway. Vinegar will remove rust, but also every trace of bluing. Warm thoroughly to dry afterwards and dunk in your favourite oil and you're done.
