I only have a "few" nickel plated Smiths. I agree with FYIMO in that I do not think there is anything better looking than a well kept nickel Smith. Just my opinion, but that is why I have a "few" of them.
If I had a chance to buy a nickel M13, that was P&R, and in very good condition, and at a decent price, I would own it. I sold the one I had, and have regretted it since.
