Hello everyone!

This is my first time writing on this forum, actually the first time writing on any forum!

So, I bought this bike several years ago when I was in college, - I quickly needed a fast form of transportation so I bought a bike of Craigslist since it was all I could afford. The frame was clearly repainted, but he claimed that it was a Cannondale. Today, years later, I decided to strip all the paint off to start a small bike project for myself. I found the serial number and would like to ask you guys and gals if you could help me find the manufacturer and year of the frame.

WHAT I DO KNOW:
Track bike
Steel frame
The serial number: Letter 'G' followed by ten DIGITS in a single line on bottom bracket. The last three digits 199
(I have checked online to see if it has been reported as stolen, it has not.)

Is it indeed a Cannondale frame?

Thank you all for helping me find this out.
