A question a Surefire M3 interior Coat Color

Recently I bought a crosshair M3 from a SF collector. But I find that the interior coat color for this M3 body is clear but not yellow color, which is common for old SF flashlight.

I am pretty sure that this is not a courterfeit, I am just wondering if Surefire produced some M3s without yellow coat for some reason before?

Ah yes, you do have a good point there. If you have a set of calipers, check the ID to see if its been bored for 18mm cells.
Also, just a quick visual will do the trick; unmodified bodies should have a slight inner lip in the ID, about 3/8" from the tail end.
