As a self proclaimed Motron expert, I have only seen that tank rack on the green metal flake Medalist. They did come in silver/gray, but I have yet to find a brown. My 3 green Medalists all came with spokes, not mags, as well. Maybe if you remove the plastic cover in the "step through" area, the true color might reveal itself.
Who knows. I've seen 3 different types of seats, cheap rubber, leather(ish) short, leather(ish) long, mags, no mags.
Either way, $200 for a complete non-runner is pretty good in my book. Of the 10 I have, 5 were at or under that price, and I, a motor moron, was able to get 1 running all by myself by tapping loose the piston and hooking the carb up to a temp tank after cleaning it.
Update: I've only seen the chrome plated bars by the foot rests on the green bikes as well. Black models had black bars, while most others had none.
And, I'm obligated to say, "Yay! Another Motron rescued!" (edited)
