Greetings everyone

I'm considering buying my first CB750, this is something I have been wanting for some time now, but sadly, where I'm from there isnt any available for sale in the whole country.
There are a few dozen original CB750 that were sold here, but everything else has been imported.
I'm from Europe, so the most logical option is to import from countries with a high number of sold CB750s, like France or Germany.
Just for context, the only 750 I saw for sale locally (which had been imported from the USA, then to Germany, then to my country) was a K1 at around 10000 euros, with a lot of issues. It did have HM300 exhaust on it, but I ended up not buying it.
I've recently come across this one, a "K6" imported from the USA to Germany and it is for sale at a price of 4000 euros.
I would like your feedback on it, as I see some issues already with the bike. Since I cant see it in person as I do not live in Germany, I want to make sure I'm doing a solid purchase.
Here's an album with some photographs the seller shared with me:

- Seller states 1976 K6 but it doesnt look like it?
- Petcock is on the wrong side for a K6
- Instrument panel is K2 or K3
- Front fender is 1977 model
- Last ran in 2012, but engine turns over
What else am I missing? Excluding the tail light and turn signals, as those were changed to comply with German legislation. I'd eventually replace them with USA period correct style.
Does it seem like a solid base? My goal isnt to go through and restore everything, I'm looking for a mechanic restoration if needed, and use it as as is with minor corrections.
Thank you for your time
