I had a bunch of old panel meters and needed to find one with a certain scale. Of course, I didn't have the correctly scaled meter.
Here are 2 different ways to re-scale the meter:
1. Use "White Out" or white model paint to change the scale markings. Ie; remove the MA and change to A.

2. Remove the meter face. (Easy to do on the old Weston 301 series meters., but the hermetically sealed ones don't lend themselves to doing this too well.)
Make a new face for it and glue it to the back side of the meter face. Reinstall and its done! (Or you can repaint the back side of the meter face, and hand draw it on using India Ink.)
 The nice thing about this is if you ever junk the project, you can just flip the face over to get the original markings.

You can photocopy the original scale or scan it, modify it, and make one the exact size on your computer too.

 I have hand drawn ones and re-marked them for years. I have used contact cement to install them with good success too. Some are still looking nice after 30+ years.

I was mulling over in my mind, about finding some old 200 micro-amp meters, the size used on the TV-7 tube testers. Measure the resistance and add till they read a total 2940 ohms. Then Remark the faces to read 0-120. Or find some 12 volt scales and see if the lines would line up by comparison.

Those stupid meters are going for around $150 each. I am also thinking about using 0-100 micro-amp meters and adding a shunt to bring meter sensitivity down to 200 micro-amps and going from there.
Just an Idea at this stage.
