Hi Jason/Sir Bat,
yes the previous owner did go a bit overboard wit the paintbrush on the logo didn't he :-)
It's great that you now have a 'provenance' (? I suppose?) or at least history for it, you should record all those details before they slip form your memory (and our history)- people, places, dates, times, anecdotes.
I knew I had seen that type of exhaust somewhere else a long time ago, just can't remember where. Maybe an old Lister motor...?
I don't think there's fluting to the blades, can't see an 'fan blades' on the blade carrier, jsut those holes... would the grass ejection have worked OK?
Just to play Devil's Advocate: except for the dodgy Victa anagram name, are we sure the Vi-Cat came after the A-V: how do we know that A-V didn't copy the Vi-Cat design???
Cheers,
