Replacement tiller handle for a 470

Hi guys,

I've bought myself a 1974 470 to teach my kids some sailing. Haven't sailed in close to 20 years. Long story short, it's a work in progress with repairs etc, but something we can all do together. One thing we are coming up short on is a tiller handle. I have the original which is incomplete and very dilapidated (rotten) and probably not the right length or shape. Does anyone know of a supplier or someone who makes them (prefer Aust). I've had a go at making one, but it doesn't seem right.

Thanks in advance
