I've seen cream on at least the VC-160's, VC-125's, as well as the MKI VC-Mustang & Sports, and MKI&II Auto Drives, as well as a number if S70 Utilities.
I'm still curious about the blade disc on my NOS VC-160, which as Joe pointed out, is bare metal, which in my observation, and yours I beleive, is abnormal.
I have a few theories:
1) variation based on availability (at assembly there was less than needed painted discs, or a failure of some kind)
2) variation based on experiment ( like the 3Q, 3S and G2 carburettors being released in batches on the same mowers in a post release test)
3) variation based on recall (perhaps some, or all of these machines were released with plain discs like my nos one, but some time, say maybe 1974 or 1975, there was a recall, perhaps the paintless ones rusted to easily in use, too much rust at the blade hole could weeken yhe thin metal area betwwen the blade and the edge of the disc, or it may have been as you say visibility)
Or, maybe there was just a mistake on that mower.
As for the blades, next chance I get, I'll stare close at them, i recall a victa stamp on the bolts, but i cant remember if there was one on the blades...
