While looking over those photos I noticed that, and wondered if it's the same prop.every single HAL faceplate seen in the film, and in behind the scenes photos, has exactly the same proportions.
That film had a big budget, right? I suppose they wouldn't have had to skimp like that.
BTW I remember going to the theatre when that film opened- it was the first time I'd seen a line go round an entire city block.
