Distinguished from a Bdsm Style Catherine Wheel the St Andrew’s Cross shows up in very early bdsm photos. Other names are crux decussata, X-cross, X-frame or saltire cross.
There are not many photos but I was able to trace some (if you happen to know some old ones please let me know)

Whipping frames based on the standing X construction were in use for judicial corporal punishment, e.g. in 19th century British prisons. I included one photo to give you an idea.
