yes, thanks, these are very helpful. It looks like the legs in my Ludwig drum are mounted the reverse of yours (the clamp part is the same mounting, orientation though). I'll try changing mine
(... fast forward to the next day...)
Here's what I've learned...
On the bass drum I have, when I undo the set screw, etc., and swap (reverse left-right sides) the legs, and mount them so that they insert into the front of the shell-mounted clamp, the legs barely reach the ground and are much less supporting of the drum. Plus, when I fold the legs toward the shell, each leg then bumps directly into the top of a lug (on my drum there are separate lugs for the batter and reso heads).
When the legs are returned to their original placement, they are more supportive and are able to fold directly against the shell without bumping into anything. Compared to modern drum spurs, they're still not quite as solid, but fairly usable . To increase utility is what got me on the hunt for supplemental hoop-mounted clamp-on spurs, and so far (see my first post) presently I am the proud owner of what is plausibly a factory mishap(!).
On your gold bass drum, the legs cannot fold directly against the shell due to the single lug design, and will end up resting against the tension rod even if swapped to the other side (i.e., in either orientation, I would think).
Not having other similar era drums to directly compare to, I'm wondering if having the legs inserted into the rear is how they're supposed to go (on your drum too?)? The rear of the clamp is angled such that it is closer to the floor and when legs are inserted thusly, it would seem to give more room for support and adjustment (at least in my instance).
