I am attempting to take apart the shadow meter that came with Philco 16B. I believe this is the early type of shadow meter. I removed the bottom panel to expose the vane inside. It looks like it has a screw that holds the coil on top. I then removed the top panel to expose the coil.

What would be my next step? Do I remove the screw located below the vane which I believe holds the coil on top? Do I remove the screw with a metal flat head screw driver? It seems the vane could easily be damaged by removing the screw.

Once the top coil is removed will I be able to mount it on a battery powered drill and rewind the coil?
