A shot in the Dark

[alex e.]

I figure it cannot hurt to ask.
a friend and I are waiting for  Riffle Shoppe parts.They cannot get a 51" Barrel made.We were promised the dimensions of a barrel for said gun as per the original piece. they have been anything but expedient in getting them to us.
The question is: does anyone have the barrel dimensions to their "French officer's fusil"[actually its an anchor marked trade gun]  I believe its the gun  in Nueman's " Battle weapons of the American  Revolution.
We would be forever in your debt if someone could assist.
Thank you in advance.

Jim McLemore in Hebron Indiana can make barrels in excess of 51". His phone # is 1-219-552-4050.

I have a man to make a barrel up to  60". i need the dimensions off the original piece.
I should have been more clearer.
Thanks, Alex
