HP-41cv trim/bezel brown?

[rexbinary]

Hi all,

I was looking at my HP-41cv with a small flashlight and for the first time noticed that the trim/bezel that goes around the sides and bottom of the unit is actually dark brown instead of black as I thought. Has it always been brown and I just never noticed? Well, you can't answer that obviously, but maybe someone can tell me if all 41c calculators have always had brown trim/bezel?

Thank you!
