Gonna guess those are a little newer - have the round tom mounts, they definately look much more silver than mine (even under the hardware where it's not faded, mine look much more pale?) My 16 and 18 are both floor toms, your 16 (assuming 16?) appears to be a mounted tom? Pretty set though, and some of the hardware is good to see, gives me a visual idea of what I should be looking for. Anyone have a source for the floor tom leg mounts? Most I've found are like 1.5" or 1.75"? between screwmounts, these are closer to 2.25 if I remember correctly? Most were damaged, and the remainder are currently in use on my "daily driver" (mutt) set - holding my 20" Slingerland off the floor (it had a wider hole spacing yet, but was already damaged enough that I wasn't worried about modifying it to fit)
I have the right [70s] set of three floor tom leg mounts for your set.....Mikey
