I sent an e-mail a few weeks ago and this just fell through the cracks. It could be the address I had is bad.
As to why I need one, I always find ellipsoidal parts for cheap (pawn shops, ebay, etc.), so I buy them when I can. I have numerous shutter assemblies and reflector housings, but need end caps and lenses for them. I thot I found an end cap for $15, but it was the wrong part # and no photo, so I passed.
