Ironport

Hello! Does anyone happen to have a recipe for a western states fountain drink called Ironport? I am desperate to find what might the ingredients in this drink.

Thank you!

There was an awkward silence and I felt a little pressure from the people behind me waiting to order .

I then blurted out the first thing that came to mind - Rum and Coke.

That made me think. There aren’t many drink recipes on the site.
