Ed, I don't think it's a knock for John to note that the case hardening colors a particular gunsmith produces are inappropriate for a Parker, or other gun. Some people don't care if the refinishing they have done is correct and as close to Factory Original as possible. But many guys do, and that's the difference between a proper Restoration, and just plain refinishing. I note that there are very few gunsmiths who can turn out colors that look correct for the Syracuse Lefevers, which tend to be predominately blue, with ghosting around the edges and screw holes, etc.
Knowing that Mr. Graham produces case colors that would look correct on a Colt SAA is valuable information for guys who want that appearance. Most guys who do Color Case Hardening settle on a technique and particular combination of charcoal, temperature, quench, etc. So while no two will be exactly alike, we can predict who might give us a result that is close to what we desire. Then we are less likely to be disappointed when the parts are returned.
