[DMXF]

The one in that picture looks like from the small batch of wheels that were made by M&A Castings and sold out the "back door" using Halibrand's patterns around 8 years ago (Halibrand was not pleased). The machining/details were not worked out at that time, as new patterns and machining programs were developed to make the wheels more accurate relative to the ones made in the 90's. This "work in process" state can partially be seen by the step on the inner diameter of the dish where it transitions to the casting. Halibrand never fully completed development to go into regular production again, although the outstanding issues were supposedly not too difficult to resolve.

Availability of new correct magnesium Cobra II wheels would be nice, I would get a set myself for safety in track events or other anticipated severe usage, keeping the original wheels in storage. However, I would want to see, in detail, what the new wheels look like in finished condition, front, back and sides, before putting money down (getting the wheels right involves repetitive samples and comparisons to the originals). M&A had to make new patterns, because Halibrand took the other ones back, so everything is basically starting from scratch, although M&A has the advantage of having make them in the past.
