A quick look at Jörg's site shows that even the non-"A" SR-51s had yellow keys. So it must be a frankencalc with components from an SR-50.

I accidentally happen to have those units and yes; that could be. It could also be at the end of the run and assembled from whatever fit. To prove that though; we'd have to check serial numbers. I know National Semiconductor would "make the best of a bad job" with what parts were at hand.

Let's believe in the frankencalk.
