I have been offered an old but hardly used omnipole trailer system which i am trying to get a bit more information on.The box with all the parts in is stainless steel with a few dials on but could anyone tell me what water capacity it would be without me stripping the machine down.I don't know if there were a few models during this era which i would guess at about 10 years old.It has the original cover over the trailer frame and also three different sized fibreglass poles with the original brushes.They are considerably heavier than the carbon poles of today.I thought i would try on here before contacting omnipole as i have only just seen the gear tonight.Cheers
