Yellow & blue streaked glass elephant

I bought this elephant from a lady who had several pieces of Mdina and I thought that the colours were similar. Any thoughts please

I know what you mean (see photo of streaked and grizzled Mdina weight) - but remember Mdina were not the only ones to produce this sandy yellow streaked iridized with blue glass - In Scotland we have Ed Iglehart and T Young to name but a few (I have some Iglehart mushrooms) and Sunderland famous for its glass has many workshops (The North East in general) so maybe a bit of detective work is needed.
