It is most definitely a reproduction. It was made by
Steve, AKA
"obtronix". I've been watching him sell the exact same package on epay
for a couple years now.
I contacted Stephen last night to see what he was up to. As it turns
out, the kit on eBay is one of his that the buyer probably gave up on or
never had time for.
He's planning to make some more kits and he's working on a web site:

It looks like he's off to a really nice start!
