CALLING ANY AND ALL PROJECT TURNTABLE OWNERS

I am posting this in the hope that somebody with a Project turntable that has a belt going around the circumference of their respective deck sees this post.
The reason for this was that I would be very grateful if the owner would kindly use a set of digital calipers to measure exactly in milimeters the 33 1/3 and 45 rpm pulleys. BTW this must be the 50hz ac motor versions.

thanks
