Advice on setting up an outline..

[drew]

Hi folks, i am tasked with updating a badge shaped logo, and the only graphic i have of the original is a poorly scanned version. I thought to recreate it, finding many examples of badges in jpg format. I have attached one example of the outline i need.

My question, what method would more experienced graphics gurus use to setup the outline within Extreme? I have experimented with the bitmap tracer, but that is not good enough. I think i might simply have to trace it with the line tools, then fiddle around, but was hoping for something more consistent than my clumsy efforts. I also figured i could simply render one vertical half, then clone and reverse it to ensure exactness.

I would greatly appreciate your thoughts. Cheers, drew..
ps: i have blurred the image, but if even this is not appropriate, i apologize, and thanks for setting me straight Ü
