[R-390] pulleys

[Kenneth Arthur Crips]

I have a question.  I have a number of old receivers that have string moved tuning dials.  They have little plastic pulleys the string moves and there are bunch of these little pulleys that have broken off.  Do these pulleys have a specific name so I can look for them, and does anyone know where I can purchase a bunch of them?
