ok, so numerous variations of 7 segment LED's are available, but it appears if you want to mount them neatly, options for Bezels are extremely thin on the ground.
I am only after a bezel to cover 6 to 8 7 seg (14mm, commonest size) with or without the contrast screen, which is still readily available in sheet form.
The bezels we previously used were from RS and perfect for the job, but are no longer manufactured.
