Sorry Grumpy, i was taking the piss.
I have a thing about electric powered things, cars, bikes and mowers and the like. By the time you take into account the enviromental impact of making the batteries and their end of life disposal (wich will be the next big thing with recycling, disposing of contaminating recyclalble waste products, acids oils non lead acid batteries and the like) they actually have more of an impact on the enviroment.
Still would be handy to have a bbq and know you are never going to get half way through cooking the snags and find out the bottle is empty.
That Viking would have been made by Masport. Looking at the second picture the catcher almost looks like it is painted.
10ci quattro motor by the look of it.
Ive got a Viking here, its on a diferent base, takes a frame and bag catcher, im on the lookout for one that will fit it at the moment.
