After a long search the NOS no-logo wood knob arrived from Germany today (along with some german candies thrown in by the seller) and it looks super nice. Here are the knobs lined up for comparison. Left to right: leather & logo (which came with my car when I got it), wood & logo (from Germany), the NOS wood no-logo, and a reproduction no-logo I bought from Germany a while back:
You can see the original ones are the same height and shape with pronounced dome, the repro is a little shorter with slightly smaller circumference of the top.
The new acquisition pictured in the car, it matches the wood nicely and I will roll with this one for the foreseeable future. I'll be selling the repro for a bargain if anyone wants it, its a nice knob.
