Re: Hello from Australia
The headlight is an old bicycle kerosene light. I've put a modern Cree light assembly in it. ($10 from E-bay Hong Kong). See pics.
The tank is from eziridecycles.com.au here in Sydney Australia. I believe they are from China that some vendors sell. They will fit on the bigger bikes that have enough room under the cross bar.
That's cool that you've been to Perth. Small world.
Yea, Emu Bitter is a nice beer, although I prefer Victoria Bitter (VB).
