Any ideas what this font is?

Thanks

Cabriolet  Suggested by donshottype 

The chrome emblems of 1950s vintage cars have inspired several connected geometric scripts
The closest to Customline could perhaps be Cabriolet and Hooptie Script Italic http://myfonts.us/td-jkuh6m
Also Permanent Waves http://myfonts.us/td-XHxIxr and Rocket Script http://www.dafont.com/search.php?q=rocket+script&text=Customline
