For your consideration one Thomas RoundBall to RimFire Vol 3 bullet 800 Early Colt "sugarloaf" .44 cal. "Dragoon" bullet. You will find this bullet to be in excellent dug condition. The patina is a real nice white color...just as shown. A protruding base cast mark is easy to see. Measures about 0.44 x 0.68 inches (just like the one in Vol 3). This is possibly a Colt Walker bullet. 

Thomas states

a smooth sided "picket" with no recess above the base for attaching a powder case. If you have the 1st Thomas handbook (1996 no revision) I think that bullet is listed there but I cannot find my copy. Often mistaken for a picket bullet. **Well I found my copy of the first Thomas handbook & there it is bullet 11 Colt Dragoon. I do not see it listed in either the revised 2007 or 2013 editions??**
