It is missing the ram rod. The length of the barrel is 29 inches not including the tang that holds the barrel in the stock. It is marked 50 Cal. Any one have an idea of the length and diameter of the ram rod that was original to this rifle?
You got some good advice up above (filing it smooth).
I have a new-old-stock still sealed-in-original-package Treso ram rod (the aftermarket synthetic version) made for the TC Hawken; PM me if you are interested and I'll sell it to you for the bargain price of $10 to cover postage & handling. $10 shipped is your total cost.
And if needed, I can add a picture of it (with my user name & date) here on this posting to confirm I have it to sell.
