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 its purpose, I would appreciate your help.
The arm is not from a P14 it is from a Lee-Enfield.

No way of knowing what rifle the sights were intended to be used on. Pehaps there was a base so that the sights could be used over the bore.

If it was used over the bore it would have to be reversed.

I'm not refering to using it on a LE or P-14 installed on the left. Wondering if they might not have ben used with a base such that the pivot was on the right.
Same sort of idea as the Cooey base which allowed a Ross sight to be used on a SMLE.

No I don't think its for that assembly
I have a few of the "HWC" for Howard .W Cooey marked rear sight for the .22 Canadian No. 2 Mk IV* SMLE. It was a conversion used on the SMLE training rilfles it uses a base suitable for the standard sight for the Model 1910 Ross.

My guess would be that these were made up to use with Galilean optical sights on Long Lees. Maybe something put together for sniping in WWI when "Long Toms" were used for that.
