I have just a few British guns, but I have noticed that the rust bluing (blacking) vary between my few examples;

Jos. Harkom 16 bore BLE (re-barreled by Hellis, Beesley and Watson in the late 50s, Birmingham proofs) These barrels are moderately polished and VERY black.

Dickson RA - Re-barreled by the makers in the 60's (Birmingham proofs) these barrels are highly polished with a deep, glossy plum colored blacking.

Henry Atkin SLE - made in 1930 and barrels original Vickers steel but refinished at least once. Very highly polished and very black glossy finish with faint plum highlights in sunlight.

Based on these descriptions, which of the finishes would be closest to original Brit standards?
