National NC-57
#1

I was gifted a National NC-57 receiver which I’m
slowly rehabbing - winter and illness are slowing me down. The electrical part is strait forward. 
The dial mechanism works but is so dirty and cruddy that it will need to be disassembled and cleaned. 

I’ve found replacement dials and dial glass are available. My issue is that the dials are held on with rivets. Drilling out the old rivets not an issue. I see 
Is there a riveting tool one could use for a round dial with the rivets in the center ?I’ve not used a manual rivet gun before so I’m not sure if that would work. From what I’ve seen it appears it might work. Before I blow $30 at ace on a pop rivet gun can someone confirm this will work.

 As an additional issue the dials have no parts numbers. I’m assuming the replacement dials from Radio Daze will work, but I’m not sure.
