Hello,
Thank you guys for your comments !!
I think there are missing two small screw piece for fix the wick...
For take it back, I will merit it :
The auction house is 500km far away from home and it's really difficult/impossible for them to send it because it has a really long handle:
more than 250cm long overall...
a interesting return trip, hoping it's ok to place it diagonally in my car
Kind regards
