Hi Cobbadog, Diabetes is a bugger, one of my neighbors has it, he is a very fit, healthy 50 something who loves mountain biking. He has recently had several toes amputated, I`m very pleased to say that I saw him back riding his mountain bike yesterday.
I`m lucky with the melanoma issue, I spent the first fifty years of my life in the UK where the sun only shines for a few months a year, guess I`ve got a bit of catching up to do.
My Father in Law had glaucoma, diagnosed in his late forties, still driving in his seventies. Best expert in Australia is Dr. Ivan Goldberg in Macquarie St. Sydney.
I have a mig welder an AC/DC tig welder, oxy/acetylene equipment, stick welder and enough welding rods to rebuild the harbor bridge, I will happily load the whole lot on my ute and drive to NSW to watch you try to weld wood together!
I messaged the guy with the J 4 1/2 he hasn`t come back to me yet, just another fool who thinks it`s valuable because it`s old, more than enough of these in museums so only of interest to vintage engine buffs like us.
Good luck with the medics,
Bob
