Metal 500 finger wheel dial card holders

[m1898]

I have a couple of WE 500 metal finger wheels with plastic number card rings. The rest are metal. Was there any particular reason/timeline for the difference?                 Jim

Jim - I believe the plastic ones are a 70s item, and I'm sure it was less expensive.  The plastic also don't have paint to chip, and since they are more flexible, they are a bit easier to install based on my experience.  I personally don't like the plastic ones because I know they are newer and not 50s "authentic".  They are also a bit thicker than the metal ones, so a careful eye can spot them pretty easily.

Makes sense. Thank you. I will be replacing the plastic with metal, soon.         Jim

The plastic one also breaks easily, especially the tab on the bottom that holds it on the dial.
