Here's an offer of some  shallow troughs available for uplift in  Edinburgh. 
Jo D. who is offering them to a good home, says:
 "I have 4 troughs going spare that need a new home rather than landfill. They appear to be troughs that have been made to look like stone using the good old fashioned cement mix. They could do with some tlc but may be of interested to one of your members. If so please can you pass on my details to the person so I can arrange to pass them on to a new home."
 Here are  a couple of photos of them .....


I imagine  Jo would like  to rehome these troughs sooner rather than later, so  be quick to let me know if you're interested and  I'll  give you  her contact details.
