I stumbled across this in a deep Google search. and it's got interesting lines. But with that DIY-in-the-dark paint job and the handle being hidden/held on by a plastic bag, the Australian seller of this random, old kid's rocker should probably change "very good condition" to "nicest example in Shailer Park." Which is, I believe the one stop before Woop Woop.

How weird to see you mention Shailer Park, and yeah, ths rocker does sum it up. It's an outer suburb of the city I live in, it's not woop woop, the city is the size of Houston.
