If your 1970's 110 has been well cared for, chances are the action will look much better than any cold blue job you could do. In 2008, I had an ER Shaw barrel made "in the white" and cold blued it myself. It matched the Stevens 200 action I installed it on almost perfectly. But, of course, they are not known for a "beautiful" finish. But the cold blue has served me well since then, and has needed no touchup.

A beautiful blue job, rather hot dipped or cold, is dependent on the degree of polishing done to the metal before the blueing process. If a barrel has machining or sand marks in it, they will be there after the blueing process, whichever method is used.

I have seen where many have said they got the best cold blue results with Brownell's Osfoblue.
