Early version of Ross Mk III sight.

Would the experts here say that it is?

Aperture is rather small.

Any reading material as to properly stipping down the sight for maintainance?
Took two days to free the windage plate and knob.

Yes, that is the early version of the sight on the Mk. III rifle.

Clean the rifle with easy off oven cleaner and the sight will come up fine too. http://www.canadiangunnutz.com/foru...17-Ross-rifle-(Sort-of)&p=8578415#post8578415.

Or you could punch the axis pin out and put the sight alone in an ultrasonic cleaner with a good strong degreaser.

Heat it up to get all the moisture out of the cracks and crevices and then spray well with WD40 or G96.

Rifle looks to be in decent shape. Does it have "HG" and then a number on the barrel?
