Cranberry glass has been popular for a long time with many producers, logically many makers would have liked to supply any large market. Another complication is identifying individual makers during the Victorian era, many no longer exist and have been forgotten, with the makers we do have some knowledge of that rarely includes good documentation or catalogues. Another twist is that producers today still make wares that can be very similar, a couple of examples are Horncastle Glass who still make fabulous epergnes and Exmoor Glass producing in cranberry:
http://exmoorglass.co.uk/shop/page/4/Given these limitations often the best we can do is say it looks English or probably Bohemian. Many people when selling want the certainty of a name, especially if it adds status. Saying all that your basket has some distinctive features that may or may not help. The prunts (they look like berry prunts) are one, at various times that decorative feature has been used in this form in Italy, England and Bohemia. Your basket looks like it has some gold leaf and the exaggerated pinched waist and all the decoration point to a quality bit of production. The style of the pinched feet might be the best pointer, I often think Victorian and Bohemian when I see similar but would not rule out England as the country of origin - someone with a better knowledge of Victorian glass might be able to comment on that.
I think Salviati is a highly unlikely, just not their style. It is so easy to allow wishful thinking to sway yourself in these searches!
