some fun for half an hour working it out

X-2000 X-2000R tension arm roller black cap I do not make theseI have had these on my desk for weeks, I have come to the conclusion that these are the ultra rare tension arm roller cap for the X 2000 series , that was the last reel to reel they made for the hi fi market. I have never seen one , but I know its super finnicky on its transport side. Owners who have them preferred the earlier X 1000 types I am still not 100% sure on this so I have included the dimensions , these are impossible to find
