No problem, the original Amiga font used was Bodoni, I searched the web but the closest I came was the BodoniFLF font which I used for the (r) and Workbench 3.1 text. It misses the curves on the Bodoni font used for the original Amiga logo. So I decided to search for the logo on the internet.
I used the Commodore logo here and the Amiga logo here (scroll down).
And here's the template for the Gimp I made.
Actually, the Commodore-era Amiga font was ITC Garamond. Bodoni was used in the Amiga Technologies era.
There were some gallery images posted in May 2007 identifying the Amiga, early Commodore, and later Commodore typefaces, but they seem to have been deleted! I was able to recover some thumbnails using the Wayback machine, but there's very little distinguishable on the Commodore fonts. There's a bit more visible on the Amiga font.
