Interesting. You're building ERA #752, and I built ERA #452, so our Cobras are exactly 300 cars apart. When I built ol' #452, I documented the entire process and published a book with the concept-to-completion story and about 50 color photos. More info here:

If I can be of assistance to you, post questions here or send a PM or e-mail message to me.
