I found the eBay seller, search "woodhead studio" they do a range of scuttles in a range of sizes, the scuttle is fairly inexpensive, BUT the postage is a killer.
They are nice though.

Quite a few I'd say, like I said there is a guy in the UK who sells on eBay, i reckon a searchfor scuttle would turn it up.
I think a two part scuttle would be nice, but the top bowl would need to...

There is a thread somewhere regarding some nice handmade scuttles. They are avail on eBay, and aren't that costly.
I really can't remember much else, but I am sure you would find the thread easily...
