1841 Mississippi Colt Conversion

[whitneyrifle]

Hello to all! Just recently acquired an 1841 Mississippi produced by Whitney with a lock date of 1855. It has had the Colt conversion done with the screw on bayonet lug, Colt revolving rifle sight and bore to .58 with 3 lands and grooves.
Posting a lot of pics to garner what ever information I can gather. I know Thorton cartouches the stock, but there is one cartouches that is undistinguished and the other on the butt is the Colt Conversion cartouche, but not sure who the inspector is. I am familiar with the JH as a common inspector for Whitney on the barrel, and I believe (I could be wrong) the 3 CC is from Colt.
I've posted a lot of pictures so you can look over and decipher what you can.
Where I am lost is at the breech plug area, the Z mark and the numbers are a mystery to me. Any info would be appreciated!

Wow, I have a very early Needham Conversion #3, that has the same font Z on all the conversion parts.

You accidentally posted a picture of a Zamboni with the rest of the pictures. Not that I disapprove of such things.

This is based only on what I can make out of the photos. The long oval most likely WAT for William A. Thornton, The short oval GW for George Wright. The long rectangle nothing I can make out. JH on barrel is John Hawkins

Very nice addition to any collection. Congrats. As to the Zamboni… it's certainly not the worst way to earn money to feed the addiction. Plus you get the bonus of money from the tooth fairy for all the teeth you find.
