Thanks for posting the pictures guys!!
You will note that the Jigging varies quite a bit.
GEC had some production adjustment they did midstream, which caused some interesting variations! I don't know if they had to repair/resharpen the heads, or what. It happens now and then, and mostly goes un-noticed, but it is more evident in this run. The cool thing is, you can see Rodgers Bone, Ka-Bar "roof-shingle", and some NYK or Walden characteristics!
