I have a question, hypothetically, an early 50's k22 combat masterpiece, the unicorn nickel guns. Wouldn't they have a blued front sight, along with the rear, and were any of these nickel hammer and trigger? I have located one, and suspect a refinish because of these oddities. Were any of this model done all nickel besides rear sight? It was done extremely perfect if done aftermarket, I see no signs of work done to it.
