Mrs S wants a bucket

Yes, really. We already have several, but she wants another. Those that we have are all in use in one way or another: two have small gardening tools in them - trowels, secateurs, gloves etc - so that they can be easily carried around the garden; two (including one large builder's bucket) are full of pears I picked a few days ago; one is in the kitchen cupboard and is used, believe it or not, to carry water. But in any case, all those buckets are made of plastic and what Mrs S wants is a metal bucket to put over the rhubarb to force it. I have tried looking in all the usual places - DIY stores, garden centres etc - but although I can find metal watering cans, there are no metal buckets. There are metal planters which would do the job, but at £22 or so I baulked at buying one of them. So, next week, while we are in France, we shall scour the second hand shops to see if a suitable bucket can be found.
