MiG-19 (Shenyang F-6) on pole at Lusaka City airport?

Having searched years for any picture of a Zambian F-6, I last resorted to Google Earth in a desperate hope for any blurry shadow that can be interpretated as an MiG-19.
At Lusaka City airport I found something apparently on a pole as a gate guardian. For me it looks like a MiG-19, but from a very crude estimation of the span of that aircraft it could be a MiG-17 aswell.

What do you think?, the shadow below the aircraft has in my eyes more of a MiG-19 shape.
If it is, there is atleast an indication of the camoflage scheme of a Zambian MiG-19! Nice to see that it does not have a boooring natural metal scheme……
