Giacosa Luciano, GLB, made revolvers imported by EUROMANUARMS . Euromanuarms was created in the 60s by Giacosa Luciano in Brescia who distributed antique weapon reproductions he made and then distributed in the USA under the brand name Euromanuarms. The marking on weapons was the same stylized GLB punch. Giacosa also supplied EIG with some of their replica revolvers.

After the disappearance of EIG, Giacosa Luciano continued to supply EIG's successor, FIE (Firearms Import Export), until 1971, then gave way to Esterina Riva, the PR logo. GLB no longer exists.
