This is, I hope, is going to be a kind of short and sweet review of what I know about the early history of Italian reproduction BP firearms.
In and about 1956, a group of American investors and businessmen took a trip to Europe to tour and look over the arms making industry. One of the ideas was to see about getting American Civil War arms reproduced for the up coming Centennial of the ACW.
Beretta was one of the last places they visited, and Beretta was not interested in the project either.
Beretta had assigned Louie Amadi, a production manager at Beretta as a translator for the American visitors.
When Beretta turned the project down, Louie Amadi contacted Bill Edwards, who had brought and original 1851 Colt Navy with him to use as a prototype. Louie thought he knew of a manufacture that would be willing to undertake this project.
This manufacture turned out to be Gregorelli. This is the beginning!
Sometime later, perhaps in the mid 1960's Louie Amadi bought out Gregoelli and renamed his manufacturing plant Armi San Palao, but kept the Gregoerlli Makers code of GDG on their producs. This would become Euroarms in the early 1970's and Euroarms of America (EoA) by 1875.
I hope this info helps.
My best,
Blair
PS; this message would serve well on the thread requesting info on Gregorlli / Uberti. Perhaps, the Moderator could copy and paste this reply on that thread too? (I am unable to do this with my current setting)
