EIG (Saul Eig) was an importer of Italian guns based in Florida, basically in the 70's and early 80's. He sold many, most made by Armi San Marco (ASM) and Armi San Paolo (ASP), and most were brass framed. His mark is usually on the bottom of the backstrap. If you look at the gun closely it may have a manufacturer's mark on the bottom of the frame near the serial number (where the barrel lug meets the frame). ASM used an equilateral triangle with the letters "A S M" cryptic in the inset of the triangle. Not sure about an ASP mark. Back in Saul's day there were other minor Italian manufacturers from northern Italy trying to get into the market. Pietta, Uberti, and Pedersole seem to have put the others to rest in Italy.
I am also interested in any other repros you may have?
What is the date code on your G&G?
I have always liked the brass framed Griswold & Gunnison for the part round/part octagonal barrel and the smooth non-engraved cylinder. I have one made by Pietta (CN/2015).
Here it is paired with a Pietta Rigdon & Ansley parts (VTI) gun I assembled on a 1851 Navy frame (I had the 6 extra stop slots/approaches in the plain cylinder cut by my machinist neighbor):
