I assume that you are talking about "Tennessee Valley Muzzleloading", and not Tennessee Valley Manufacturing. Two companies, with the same initials, in the same town in Mississippi. Matt Avant does excellent work.
Lead and delivery times vary depending on the time of year, but 6-9 months is not to long to expect. Mrs.( Toni)Avant will give you the expected delivery time when you call and place your order. You send a deposit with the order, then are notified when the work is to begin, then when its about finished, so you can send the balance of the money to pay for the gun. Its then shipped to you when finished.
There can be further delays if you order something that they do not have in stock, or ask for carving, or inlays, etc. that will take more work to complete.
They have built their business on satisfying customers, so they work with you and answer your questions. If they think you are mixing apples and oranges when it comes to a particular "school" or style of gun, they will tell you, and suggest you consider an alternative that is more historically correct. But, in the end, you decide. The best way to get answers about a gun is to call and ASK them. :shocked2: :wink: :thumbsup: :thumbsup:
