@Esox ...Great SC shave today ... though the top cap resembles the one on the right in #36.
NEW SCs were shipped/sold with "any" caps? Interesting. My new NEW SC is a pretty re-plate, with bar-style handle and head style as above, right.
I do believe that NEWs' handles (well. the three LCs I have) are upside-down about 50% of the time, i.e. the patent date is by the upside-down by the head, not the ball-end. So Gillette assembly is *interesting* at times ...

The LC's don't all have the same caps either! Try the SC baseplate with the LC caps, you will notice if the caps are different while shaving with it. You may come out with a better combo.
