Folks, I can't be the only one who ever thought about this.
I wasn't happy with the power and speed of the mainspring in some of our repro brown bess locks. I've fitted a couple of original Model 1842 forged springs to some of them and it worked out great. There still are a good number of these original springs available at rather cheap prices, especially considering they are forged springs.
Something that might be useful for some members.
