Baker rifle barrel dimensions

[Sasquash]

Hi all,
I have an idea in mind: the possibility to adapt a Traditions Kentucky barrel to an indian made Baker rifle (...well, smoothbore :wink: ), but I need to know the Baker rifle barrel dimensions:

-External diameters at: muzzle and chamber.
-Flash hole distance to the plug.

Thank you all.

While the TOW barrel may replicate an original I'll bet the barrel in the India made gun doesn't even come close. I would expect the channel to be way oversize and wouldn't spend any money on a barrel till I had the gun in hand.
