Measurements pit to pit is 51cm. Have added additional photos of measurements.

Anyone know estimate of year of production and potential value?

Thanks Jimmy, I'm from the UK so had to google Tim Flannery. I'm guessing the tee is from the 80s after googling. what do you reckon the value of the tee's is?

Hi, can anyone tell me if this tee is genuine, bought it on EBay in 2006.
