Rare collectible, unique item, electric guitar, machined aluminum, original, Fernandes

This is an original guitar I received from an acquaintance over 10 years ago.
The body is a one-off, machined from a solid block of aluminum.
It was CNC machined from a block of aluminum, giving it a substantial weight. I estimate it to be around 5kg.
It's a Strat-type body with a simple single volume control.

The neck is nearly new and is a repurposed neck from a FERNANDES THE FUNCTION (possibly from the 90s?). It's equipped with GOTOH pegs (sg381).

What you see in the photos is exactly what you get.
While it doesn't come with pickups, the aluminum body resonates quite well when the strings are strummed. It sounds like it has the potential for a really good tone.
The body work is highly refined, with meticulous design and precise dimensions, suggesting it was made by a relatively well-known workshop.
I was told it was quite expensive to have made as a one-off.
Unfortunately, I haven't been able to find any similar guitars through research.
It's similar in concept to the Vincita, which was released last year (https://www.kikutani.co.jp/items/alluminio-g/), and has a list price of 600,000 yen. However, due to its unknown origin, I am offering it at a low price.
I welcome anyone who wants to try out this rare item, an aluminum machined guitar.
Please feel free to ask any questions or consult with me.
