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

[Albayo]

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.
