1805 U.S. Harpers Ferry pistol barrel

[Pennsylvania Dutchman]

Does anyone know were I can find a barrel drawing for the 1805 Harpers Ferry pistol. I have all the parts except the barrel and stock from the Rifle Shoppe. I would like to make the barrel so I can start on the pistol when I get my smoothrifle finished.
Thanks, Mark

What measurements do you need
 I have an original with an 1805 dated lock and serial number that matches the date.

Thanks Don for your reply. The diameter at the breech and muzzle if it is a straight taper, if not, diameter measurements in several places so I can duplicate it. The bore diameter at the muzzle. Measurements of the breech plug tang; length, width and end shape.
Thank You very much, Mark
