Think I have everything now on the bowl, here's a reply I got from the National Imperial Glass Museum:
"Daisy and Button. Not to be confused with a popular pattern of the same name, made by many makers. Is this the mark you mentioned? If so then that would be when Arthor Lorch took over the company and operated it from 1981- 82. Before then Lenox owned the company from 1971- 81 and the mark would be the same minus the A"
So I made a note of that so we won't forget. Looks like it's all solved and when my books come in maybe I'll be a bit smarter.
