I'm sure you aren't trying to deceive anybody but the wording of your post implies you want to make a bat appear made in the UK, by finishing it to a higher level. I hope you wouldn't make claims as to it's made origins being anything but Indian. However, a better finish always helps to sell a bat and nothing wrong with that.
With regards to finishing, I'm sure going through the grades of sandpaper would help. Buffing and using bat wax would complete the smooth finish. Decent grip and scuff as well. A bit of tlc and possibly a few extra pounds wouldn't hurt.
