Thanks,aerohead, that's awesome.
The MacLaren mirror reminded me of the funnels on the decks of old steamships.
So the 39% improvement was from the simulation? Maybe that would be supported or improved with some fine-scale refinement:
I'm wondering about a blown or molded clear plastic cap on a 3" peep mirror. It needs more testing in the second configuration.
Edit: Nope, I checked. The swan-necked swivel mount would have to go. An annular ring might replace it, swiveling in a fixed mount.
