Nice Rifle. It cost me that to put together my No4 from parts and refurbish it. Yours is orginal! Is it a longbranch? Any markings on the receiver? I use a hand loader for my No4 and it saves the brass so the 303 can be reloaded 5-6 times no problem. Great rifle I put 5 rounds in a fist sized group at 200 yards using the target sights. Take a picture of your rear sights at they machined or pressed metal?
