Yes, I think it's a Superbe, just a very few numbers earlier than yours. Was the gold on your an original colour? - it looks close to mine in every way-the headset is certainly the same, and that's the front shifter I will be using. I Will be interested to see how you build it up now it's painted.
Nice! Looks like a Superbe. Here's mine from a few months later:

Rather shamefully I've still not finished rebuilding it...
