Thanks Gents - Following up - call made, - I am not a face-book person other than log in once a year, but that might have to change (Keep with the times) - Looked at the site very helpful, when I started this project I did not for one minute realise how detailed it could become. Having said that it is very interesting and has got me in!
I'll post update details in due course - I'll have to tow the trailer to Corowa and cook up a meals for SWIM IN 2018 when its finished!
