I posted it on the FB site – Vintage Glass Identification – and a couple people suggested that it cut have been cut by Hawkes. I have added two links below with more information about the Hawkes Company.
I have seen online a few pieces with Hawkes’ cuttings and they are spectacular. This decoration is attractive, but I wouldn’t put it in the ‘spectacular’ category.
I have discovered that there is a second volume of the Bredehoft and Ream book of Heisey cuttings and etchings. It is on my wishlist, but I haven’t found a copy at the right price yet.
Just for interest I have included a link to the Every Day Elegant Glass Forum. The link leads to a copy of Joseph Balda’s patent for the Wabash stem.
