Ned, you picked up on what I was trying to point out.  With no Krags in the 800,000 numbers, how could two # in the 358,xxx range have an 8 as what appears to be the first #.

I don't have any third graders, but had my wife look at the GB carbine and she read the #as 858749.  The striker may have had a bad night thanks to Jack Daniels or Jim Beam.
