I must have missed this thread in 2017.
Combat Magnums are my favorite so I track the early ones,
A few observations, first is that I have yet to see a nickel one pop up with the early 6 groove tangs, closest was K261678, 7/56 but was reported to have 10 groove tangs and is the lowest serial 10 groove tang gun on my list.
The other nickel gun on my list not listed above is K264241, 9/56 .
On a side note the 6" version was introduced in 1963, since the practice of pinning the FS ramp to the barrel continued until about 1969-70 there is only about a 6 year window where nickel 6" combat Magnums would have have a pinned blue fs ramp.
