Thanks for both taking a look. I'll try to get hold of a few better quality pictures with a digital camera, although will be a few days before I see the vases owner again. Thanks for looking in the mean time, I appreciate the photo quality is a little poor, camera phones are never great for these things!
In terms of the base, I did take a picture, although again the picture is unfortunately blurry, I have attached it just in case it may be of use. The underside is also iridised like the main body and has a couple of very small rough points, where the pontil has been snapped.
The enamelled scenes from memory although not bad quality were perhaps a little loosely executed, in terms of the finer detail. The enamelling was also fairly thickly applied and clearly stands proud of the main body.
I will update with a few further pics, as soon as possible.
