Here ya go folks, have at it. I will be in and out all day so you might have to wait a bit for replies. Gardens wait for no man and need my attention before the storm. Damn chilly out there as well.
Aw crap; I've got to photograph something new. Might be an hour or so. Out just now, stuffin ma face.
OK, came back so you wouldn't all be kept waiting and will go out again now. Might not be responding until tomorrow (UK time) whether that's 1am or 10am, I don't yet know. Still; I hope it's suitably challenging to keep you all busy!! lol
The vent is a good guess, @Toker it has a curve to it so a hose type device might be possible though it looks more rigid. Its plastic. I don’t know, have to sleep on it
