Ilford is an English company most popularly known for photographic films and papers. Despite a variety of mergers and acquisitions and various corporate actions, they're still in business. Films, papers, and chemistry can still be purchased under the Ilford name.
They also had a few branded meters. This one, I believe, was actually made by AVO, as the design is very AVO-like, particularly with the meter face. My Smethurst is very similar, as is my full-size AVO volt-milliamp-ohm meter.
Gotta like a meter that puts the instructions on the back, where you can't lose them.
This meter was a gift from Marcus Rowland. Thank you very much!
