I don't make it back here enough to keep up, but I was checking to see if JC Julie got an ID on her smoke colored vase\bottle, http://www.glassmessages.com/index.php/topic,7119.0.html
and saw this thread. As I mentioned in that old post; the mark(s) I posted were drawn, using a picture of a pencil rubbing, which the owner did of their item and it was the first time I had ever seen the mark or anything like it.
Anyway; I am still doing the glass marks for my ebay Me-Page and just a few weeks ago some kind soul emailed a photo of one they found, which just happened to be the BRF mark, as well as a thingy that looks sort of like a Sphinx, with the name Egizia under it. http://img372.imageshack.us/img372/1289/egiziabrfro9.jpg
So apparently this is either the same company or a later company, (Egiza) reproducing BRF's items??? and still including the old maker's mark on them for some reason. The marks in the link above are on the bottoms of a whimsical kitchen canister set, done in milk glass and in the shape of old milk cans, a popular, cutesy motif here, (USA) all throughout the 1960s-70s, when the style "Early American\Colonial" was in vogue.
I did manage to find the Egiza website, which makes no mention of the markings they put on their glass, but who could expect them to, since I doubt they care about glass collector's concerns and are more interested in just selling their products to everyday people.http://www.tablewaretoday.com/Egizia-A.htm
Just thought I would update what info I had already shared here and maybe learn something more myself now. --- MikeEdited to add;
Suddenly there are many links on Google that lead to information about Egizia and their products. http://www.google.com/search?hl=en&lr=&q=Egizia+glass&btnG=Search
