Unkwown Frame, help needed !

[Sparga]

The "top nut" of the headset is missing, maybe that's the reason for the Gorilla thing.

I've checked the bb.
Italian right ?
70mm width

Yes, ITA is 70mm, while BSA/ISO 68 or later 73mm.
Also the size of the shell is different, BSA bottom brackets using a 1.375” (34.92mm) diameter and ITA has a 36mm diameter shell.

With that, it get's very likely that it should be an Italian Frame.

You only take the top nut off a headset if it's shot☹

It was an upgrade to run one of these back in the day, I imagine there were plenty of perfectly good headset top caps left at LBS’s having been replaced by a shiny anodised one.

We sold these back in the day.

I don't remember anyone fitting one who didn't have a headset loosening problem.

I'm sure some people did it for the look though.
