Out of curiosity what's the date code?
Also, those keycaps look like they're a different colour from regular black on beige Cherry. Is that just the photo or are the modifiers actually darker? It's strange that the cable is black too.
Not sure I know what bit is the date code.
There are two separate color caps light and dark caps. Here in the close up you can see F5-F8 are darker than F1-F4 and F9-F12, the modifiers are this dark color too. Sorry my lighting is causing some difficulty with this.
I have 4 of these, 3 out of the 4 have black cables.
