Hi Glenn -

I own a Daly Prussian Diamond Grade SxS model 275 and the barrels need rebluing. I know London's best guns have a "Best English Blacking" finish - like wet black glass appearance. It is my understanding it's a "Slow Rust Blue" process but it takes much longer. Which one of these two bluing methods would match the original when it was made in 1910?

Thanks,

Joey
