Surprisingly it was not too difficult. The handle was the hardest part but after summoning a bucket full of 'patience' I eventually had something that would 'hold water'!
For more information go to Brengun where, on page four of their 1/72 accessories section, you should find the buckets along with a good looking tool set. On page three, of this section of their e-shop, there is also a very nice looking bike etch.
I have no connection with Brengun apart from being a very satisfied customer.
