I've read about different styles of tub spouts, but am not sure which style this one is. The smaller hole near the end of the spout is threaded, so maybe a set screw is supposed to go there, but no set screw is currently in place and something is still hold the tub spout in place.
I've tried shining a flash light into the larger hole (near the wall, with a rounded edge) and don't see a set screw. I've tried applying pressure to rotate the spout in case this is actually a threaded spout, but was not able to unscrew the spout and was concerned applying additional pressure would damage the pipe the spout is connected to.
This tub spout is in a home that was built in 1973 in the mid-western United States.
Any suggestions on how I may be able to identify what style spout this is, or how to remove it safely?
