That engraving is called "pantographing", named for the pantograph machine used in the process...and that shown on your forkcrown is VERY typical of most Cioccs from late '70s thru mid '80s. Given the short point lugs I'd say yours is likely an early '80s, and it looks like a repaint that could be better. Nice bike, though, maybe a "Designer 80", but cold also be an Aelle frame...still, a nice ride, so enjoy.
