There are any number of good finish choices and people who do good work.
If it is stainless there are options for beadbalsting and shake and bake reciepts to suit any whim.
Could be cold blued or hot blued or Hard Chromed if it is a steel frame.
Fords, Tripp, vandenberg--the list is pretty extensive.
I am sure the boys here will come up with a number of satisfied referreral.
