We only sell the genuine Honda emblems as well, from a source in Japan. This is one of the reasons why the price has increased over the years! They are not taken from any existing JDM cars...they are brand new emblems sealed from the Honda factory. You do have to be careful though because some of the knock offs look a lot like the originals. Usually there is a tell-tale sign like the Honda label is washed out or something similar. I can guarantee you that the quality of the materials is not as good as on the originals. Some of the knock offs cannot even stand up to a rain storm, there is a thin red paper layer that will get wet because they are not sealed well!
As far as the steering wheel emblem, we do not stock these. The reason for this is that the actual FD2 Type R steering wheel emblem is attached to the airbag cover (with airbag electronics)...you are not suppose to be able to purchase them separately from Honda dealers in Japan. This adds to the cost of the emblem quite a bit, at least $500 I would guess. There might be a market in Japan for salvaging these airbag covers and emblems from wrecked cars, but I doubt there would be that many of them though. The only steering wheel emblems I've seen have been knock offs for this reason, but again, there may be a market to get limited amounts of the real ones from older or wrecked cars.
Edit: Looking into this more, I'm not even sure if you can separate the real FD2 Type R emblem for the airbag cover. It looks to be molded in, so I don't see how anyone would be able to acquire just the emblem...
