I also stand corrected. I called it a No. I, instead of a No. 1.
Good alert to using the proper discription, Thanks Son.
Apparently there are a number of grenade launcher wrapped rifles with the "G" prefix.
From what I've read, the Irish National army was only armed with rifles and or light ordnance and the rifle grenades gave them a bit of a heavier type weapon.
Hmm, I wonder if the "G" didn't stand for Grenade in their serial number inventory. I believe all of the G rifles I have seen in my research, all were grenade wrapped or were at one time. Ray
