• Dear Sirs,
  
  I am an Italian physics teacher and my hobby is to study old instruments. The object A0582 - GPO EVERSHED AND VIGNOLES MEGGER was actually produced by EVERSHED & VIGNOLES. I hope you will find this information helpful. If you want, you can also visit the website of my school's museum at www.istitutomontani.it/museo/file/index.php
  I'm sorry the only language available is Italian, but you will easily find the list of the instruments by clicking on "Elenco" on the left side of the screen.
  
  Kind Regards,
  Fabio Panfili
