Hi Cathy - sorry that I didn't spot this further question (I only ever look in the main Glass section :wsh:)
Without handling the bowl I am not sure. The colour seems wrong for an old piece, unless it is a pinkish clambroth - which is perfectly possible. Tony reports no trademark, which appears to rule out repro. Unless the mould has been used since the demise of IG/ALIG etc., (and I am not aware of subsequent use) for pink production with the TM removed, then I feel it is most likely to be a pinkish clambroth, old bowl. But - hand on heart - I truly cannot be sure.
Whatever it is, it's gorgeous.
