Baz,
On the works compyewder so can't see your flies at the mo.
Yes, It's Aero wing - Medium Dun & Cinnamon in the picture. I've this in a few colours - some from the Orvis shoppe & some from Flytying Boutique - Look on his site as he has a picture with all the colours avail, maybe 12 or so which is good for doing sighted posts and mimicking more natural wing colours.
