Thread: Info wanted on .303

I'm looking at selling this .303 on behalf of my brother who is currently overseas. I think he purchased it a fair while back, and added some of the stock parts from another .303. Unsure if it's been fired in recent times (not by me anyway). Seems in functional order - although not sure how aperture sight connects.

To those who are knowledgeable in these f/arms - what might be a rough idea of value?
