I did go visit your website, Zulu... very nice stuff there. Excellent work, too, btw.
That wild child in your avatar, though, has me perked BIG TIME!! It doesn't look "antique" in apearance to me. It looks like something modern applied to a modernized, more "industrial"-like carriage using old school techniques in its construction. That's why it's got me so stoked. Art and Engineering is what I see in that piece, very much my background all my life. To me, that muzzle spells "SERIOUS ATTITUDE!!", easily wielded into position and sturdy enough to take a close proximity hit without rendering it disfunctional. Those colors, too, remind me of my NAM era enlistment in the artillery. I take it you merely created your own dimensions off the drawing in that book compared to something you measured at the Alamo?
