Futura Script  Suggested by Somethingffs 
Machine Script  Suggested by Heron2001 

and this one I've heard is not a font - but Machine Script is close. (not that close - but well... similar.)

.....which is basically just shareware Futura Script

Just in case anyone is wondering "Machine Script" is a direct rip of "Futura Script" and a poorly done one at that.
