Huck,
Is that rim in the photo a black rim or a colored rim (nice photo, by the way)?
It should be noted that the rim you show (and, I think, all Advance-Design 1/2 ton rims) have 6 hub-cap clips (195355 has a non-original rim which might have 3 clips, if from a later truck).
RPO 387 Rear Corner Window option does not mention body-colored rims in 1953 (in the Truck Data Book or in the Specifications manual). In 1953, there was no deluxe cab option (due to the need for special metals for the Korean conflict). In most other Advance-Design years, there was also an RPO_390 De luxe Equipment option (with rear corner windows and other features).
Supposedly, all 1/2 truck rims came with wheel pin-stripes (same color as the body pinstripe, and coordinated with the body color).
I have often seen body-colored wheels and wonder which option they came with or if they were special ordered. If anyone has non-1954/55 documentation for colored wheels, it would be interesting to see (colored wheels apparently were common - my Windsor Blue 1948 panel had them and they had remnants of striping).
