I'm just not sure, after seeing on this section what this kind of purchase can do to someone

It's a model 413H, and has 6 82 stamped on the bottom. It even had a mostly full tank of fuel, and fired right up. It seems to work well, so I guess it hasn't been used much or was well taken care of.
I haven't messed with one of these since my old Boy Scout days in the 60's.
Anyway, here are the pics:
I guess I can clean up the rust easily with some steel wool, but my question is, should I repaint it? If so, where do you get original color paint?
I also have some pics of my older propane stove. It's a Primus that I bought new about 1972. I've never seen another one like it, and haven't been able to find anything about it on the internet. The tops of the valves say "Primus Seivert" and it says "Primus" on the side of the nozzle housing. There are holes in the base that appear to be for a wind screen of some type. It folds up to hold the propane bottles.
Just thought I'd share.
