This is my Hercules(rebadged Raleigh). Fixed running 46x17 and it's nice as my town is loaded with overpasses and I never have to stand up to pedal up them.

I'd do the green as it's a British bike with lots of polished bits and maybe a flipflop hub with fixed/freewheel setup. Or...or even better do a Bendix two speed kickback and lace it to some 700c rims. I'm building my wifes Bottecchia mixte up in the same style. I picked up some cork grips and nothing new was giving it that nice classic look.
