Doing some restoration of my #ludlum #model2a survey meter. The local discount store has these spray cans of acrylic primer and varnish. They dry very quickly, especially outside in the open air. I did the removable bottom, the meter face and as a test the small cover of the calibration pots.
I am going to repaint and relabel the front too but I am leaving the battery cover as is because I don't want to erase its origin ❤️ #radioactivity #metrology
