Not sure if it is Vizagapatnam we would load Amonia,NH3 there in the early 2000's/late 1990's.I know this is about 60 odd years ago but one thing I do remember about Vizagapatnam was there was a walk way up to a church and the stations of the cross were part of the walk way. Okay maybe from a different angle but? Real teaser all the same.
