    Warm white vs incandescents

    R9080 SW35 219B thanks to the extra bump of red that gives it the rosy tint so many love is by far the closest thing I've seen to an incandescent, it is still missing that "spark" but it is damn close. Almost anything else is too devoid of enough red to look any good next to an incandescent

    A mechanical update on the Corvus design. Piston design is holding up very well, minimal wear on the sliding surfaces of the piston setup, with grease still well-retained.

    Thanks sir! These days most sales are in my Facebook group as that is where the most interest is typically. For the Corvus I think the sales in my FB group will be released first-come first serve, and I will keep a reservation list here on CPF for members who don't use FB.
