F. Moser frame without frame number?

we can go on and do this for hours, even years. I'm passing the info on - if I would be a Moser frame expert, I wouldn't be asking on a forum, would I? I know that it has a derailleur hanger, who do you think took the picture? On the other hand, it has no gear shifter mounts nor pass through for any sort of gear cable.
I don't really care if it is a track frame, street frame or whatever. The only thing I want to know is about the frame number.
