Model 10 Ross Sights With Volley Sight Alteration, Need Help To Identify Its Purpose?

Just found these in my box of sights, I forgot I had them. I have had them for about 15 years and I think its time I identify the purpose of this alteration.
I have two Ross Model 10 sights that have been altered. They have been welded to the pivoting arm of volley sights. If I line it up with a volley sigh on a Long Lee-Enfield it is not on the center of the barrel but points out to the left side like an auxiliary sight, similar to the sighting system of the Bren Guns. As you can see in the pictures one arm is longer than the other. If it was used as a volley sight the front sight would have to be extended to the left to make it work.
If anyone can explain the purpose of this alteration, I would appreciate your help.
The arm is not from a P14 it is from a Lee-Enfield.

If there are a couple of grooves on the bottom round part where the hole is, try them on a SMLE. It could be an experimental attempt to give more flexibility to the Volley sights. The Canadian Army had .22 Calibre rifles with Cooey made Ross sights mounted on them for training purposes. Is the "HWC" marking on them?

BSA made a .22 Calibre rifle intended to simulate the SMLE but in .22 Calibre. Maybe .22 Martinis?

Also, at the start of WWII, some Ross rifles were modified to a semblance of the Boyes .55 Calibre anti-tank rifle. Since these seem to be offset to the left, it is possible that these sights are for that alteration.

There is a British website which mentions such strange things. Just came across it half an hour ago.

Check out (here it comes): http: //rifleman.org.uk/Enfield_Rifle_No.2_and_.22RF_Mk.III.html

There! Don't think it's a link now. You will have to close it up.

Sorry, but I'm not terribly computer-literate; these things just LOOK LIKE a proper typesetting machine but they don't work nearly as well. Lousy type, too!

Hope this helps.
