It is branded, on the break bridge, seat stay and bottom bracket - It may have had head badge and downtube stickers that have been removed.

I don't know without doing the research myself, but probably sold their own line of bikes alongside the brands of the day, so this would be a production bike of a sort, not a sample. But they will have sold in smaller numbers, so less examples will be arounf so information may be scarce on them.

Steel Vintage sold one of his bikes and included the below information. Steel Vintage Bikes - Unique Alberti Ferrara Professional Track Bike like Cinelli Laser Pista

Description:
This unique Battaglin Aero track steel bicycle from the 1980s is a real gem! It has been painted and decalled originally by Alberti Ferrara, who was (as far as we know) working in the Battaglin factory. He built this track bike for himself and painted it in his own design! We left it as original as possible. As you can see from the pictures it displays a special paintwork, the top-of-the-line seat from Selle Italia and the great Campagnolo Super Record Pista Crank. This bike including Pedals weighs considerably less than 8kg.
The aerodynamic position, the aero-shaped frame and the low weight will catapult you to high speed.
If you are looking for a really special bike with a really authentic touch to it, this it is!
The aero-shaped frame and Columbus Aero fork reminds us of the famous Cinelli Laser Track bicycle frames!

It will certainly have a rairity cache value and looks to be a good quality frame, doubt you'll find an original fork, but may be better to pair it with something unbranded as the Colango while nice, just clashes with the frame. It's all personal choice at the end of the day tho. Interesting find, I hope more information turns up and you share any progress if you decide to build a bike out of it.
