Shot Selector Large 21 "for Lobster Ball Bucket 201 machine

[DanGo]

Hi everyone. My name is Daniel and I am new to this forum.Thanks for the acceptance.
I am a new owner of an old Lobster Ball Bucket 201 machine . On my machine is missing the part called -Shot Selector Large 21" PO739.
Lobster Company said "Unfortunately, we no longer sell replacement parts for our older models like the Bucket 201".
Then I decided to rebuild the part. For this purpose I would like to kindly ask the owners of this machine the following dimensions of the tube in question: length, internal diameter (gauge) and external diameter (gauge).
Any assistance for this work and some foto of this part are appreciated. Many thanks!

I'm in the same boat. Did you get any further? I found out that the Outside diameter is 2.875 and the inside diameter is 2.625. I just ordered a 21" piece of pvc pipe from https://flexpvc.com/Reference/FullPVCPipeChart.shtml
I will just have to figure out how to attach it. Also, having no luck finding the spin adapter or the circular plugs (time caps) that control the shot intervals. I figure it should be easy enough to make the plugs too.
