Good on ya for taking on the project for a friend.
Looks like you have made good progress already.
I have to ask because I can't help myself (nosy Nelly):
What is going on with the short wood at the muzzle? Looks like a rifle to me. Was it cut that way as a kit, or are you thinking cut-back rifle/smoothbore pressed into militia service for a bayonet?
Keep us posted!
Cheers,
Norm
