OK, went upstairs to see what I have- it is indeed a Dove. Thanks to those who posted the differences, and Jay's book. Flat plate valley cover, and the water passages per Jay. Very clean, and is silver coated with something. I separated the intake from the 660 setup to get it downstairs, still a little wobbly on the stairs from my torn Achilles. Will get the nice 660 setup down in a bit and get pics
