Upper is a No.4 Mk.1 made at Royal Ordnance Factory (Fazakerly).
Lower is a No.1 Mk.3* made at Rifle Factory Ishapore in India. It looks like it's missing the brass pin/rivet that secures the band at the back of the forend.
Mismatch bolts hurt the value a little bit but they both look pretty good. Each $150-$200 ????????
