Is this vintage steel road bike worth selling or should I just give it ?

Hey everyone,
Years ago I picked up this vintage road bike for 50€, to start cycling, but it was to small for me so never used it.
I’m wondering if it’s worth something , either as a complete bike or parted out. I’m not super familiar with vintage builds, so I’d appreciate any input.

Here are some détails from what I can read but not sure:
• Frame: FONLUPT Sport
• Tubing: « Columbus ELOS »
• Crankset: TA Carmina
• Hubs: Campagnolo Record (front and rear)
• Drivetrain & brakes: Shimano 600 (headset, calipers, and levers looks like to match)
• Bars & stem: ITM Italmanubri
• Freewheel: Ventura
• Top tube has a name: “A. Chisu” – maybe custom?

Everything seems to work fine, but it could use some cleaning and new tires. I’m trying to figure out if it’s worth keeping, restoring, or selling.
I Will move out soon so I can’t keep it it’s not worth that much.
( im sorry if something is strange, tbh I used ChatGPT to describe the bike as Im not at all a bike dude )

Thanks in advance for any help or info!
