Doug,
I dug out my Portugeuse rig and compared my original cleaning rod to your pictures. Interestingly, it is not the same as either of yours, but has some of the characteristics of both!
The shaft and top of the cap is like your "repro", but the knurling on the cap and the band around the oiler is like your "original".
Mine is identical to the one pictured in Bender's book on page 437.
Afraid I have not been much help, but confused matters even more!
