Seems to be a lot of interest in tan cleaning kits. I have 2 - 1 rco45 that was a gift from a good friend (thanks! I've still never seen one for sale for a decent price!). I also have a tan arr4 cleaning kit. Every original tan arr4 cleaning kit I have seen is marked differently than the blue arr4 cleaning kits. Below is a comparison of 1 late arr4 cleaning kits- the blue one has a 64 marked spoon that has been repaired at best with a weld to the backside- not sure if it's original, but it was in this kit when I got it. The tan kit came from a good source as well and am sure it's as built. I have 3-4 of the arr4 blue kits, and all of them have the late twisted wire chain, but they are all different (like these two are different).
Anyway, 2 kits, one post.....comparison of markings:
Overall comparison of both kits:
