Yesterday I posted a help message on the Uk/European section regarding my Excelsior phonograph, but since I wonder if the Busy Bee cylinders fit. Can a forum member messure the diameters of each end of their Busy Bee phonograph so that I may check mine. Not sure why it has a larger mandrel on an Excelsior.
Thanks any help appreciated.

I have a Busy Bee cylinder machine. Using digital calipers in inches on the large end it measures 1.890". The small end measures 1.745"

Best,
