I ordered 2 of these from super hobby at about $45 usd each, Shipping for these plus another larger kit was about $8. Very reasonable and arrived in a week.
From the WNW photo reference page. There are "bumps" along the ribs which would indicate nails were used. See 2nd pic from left in 2nd row.

You can download the Wingnut Wings instructions from their site - there are color photos or a real camel in them. Also TVAL may have more photos online of the one they restored.
