Getting teak stock only half the battle, unless you are a good finish carpenter, I don't think this is a DIY job.
I 'd try a local custom sign-maker, the kind that does artsy signs carved in wood, and give him/her the existing rail and ask then to duplicate it. Maybe $150-200, but it will look good and you can be ready to go in two weeks.
Certified...in several regards...
