If it wasn't for the early hazard switch, I would have thought that bland, semi-matt finished upper dash was from a later car.
As you've said, there seems to be a wide variety around, in grains, colours and glossiness of finish. Added to which, most of the really nice ones these days have been retouched (at least) by an expert cabinet maker. (Or a talented amateur with too much time on his hands)
I just fitted this professionally done set to a customer car, a bit TOO fussy for my taste, but HE likes it!
I don't honestly see a solution to getting back to "standard" when standard is a huge variable. For my money, it's a case of picking a stain and grain YOU think is best and doing the whole lot the same.
On my car, the cappings are a matched set and have all been redone by the same guy at the same time, and the dash is an original matched grain set from a different car but in a similar lightish shade. It's not perfect, either in condition or match, but it's close enough for me and I haven't had to spend a small fortune or hundreds of hours getting it that last 10% to perfect. TBH it would have been money, not time, as I just don't DO wood! Metal is my medium and I know my limits!
