I'm not a globe expert. My understanding is, if it has a 6” glass molded flange to fit into the globe holder on a pump then it is a reproduction.

All originals have 7" bases early ones were glass then they had the threaded base with a copper collar/flange that screws on.

Here's a pic of one of my Wayne 60's with the 7" to 6" adapter on it.
