4-hole chincup - odd stitching. What era?

[GeneralCheese]

I just bought this 4-hole chincup off ebay, and when I got it in hand I noticed the stitching was different from any other I owned.  Rather than the two ends of the fabric being joined between the last and second-last rivet, it is joined at the end, and the bar-tacking elsewhere is much thinner than other chincups.  Anyone know when this one would be from?

I'd say late 40s early 50s given the brass and the size of the bar stitch. The Korea war era cups will often have the thread in a different color as well.
