speedmaster stuff pulled from Summit racing shelves

No they won't. Bare minimum it would be a million dollars for him to pursue a suit, and that's before discovery and trial. Been down that road, there's nothing to gain if you can't prove losses of at least a few tens of millions.
Even if some lawyer took it pro bono speedmaster would just change their name, again, and avoid liability, again.
If there were no legal implications, why would SM and Summit stop suddenly selling them? Out of the goodness of their heart?? Doubtful.
