Congratulations, Bruce, those are some very sturdy accessories! Nothing like the pressed tin toys one often sees, and very large. "We're gonna need a bigger engine..."
Also, glad to hear you solved your issue with eBay.

PS, I don't know why, but as you were hacking away at that bubble-wrap with the utility knife blade, I kept absent-mindedly reaching for my scissors! 
Lol...I've learned to try to "cut away" from the items as to not damage anything, the seller did a fine job on packaging. Do to they're size I'm trying to decide what engine might be suitable to power them, I'm thinking my Stuart beam might be appropriate for the task.
