B&O Beogram 3400 counterweight

Hello everybody and happy holidays! Just got my first B&O device, so I'm pretty excited! But the one I got needs a lot of work!

In brief, Santa just gave me a free beogram 3400, that was listed for parts, and it's in very sad condition, with both power and sound cord cut out. I gave it a good look and dissassembly yesterday, and was happy to see that it looks complete, clean inside, and, more importantly, that it has a complete cartridge and a needle in good condition! I hooked up a new power cord and got it to turn really well and steady, so I decided it was worth attempting to fix it.

The main doubt I have is about the tonearm. Mine has no cover where the counterweight is, and I was wondering if anything is missing from there. it looked like to balance the cartridge at 0g I needed a counterweight (an 8mm socket to be precise). There seems to be very little information about this online, and no parts listed on ebay for that, so I hoped somebody in this group would know what they're talking about! I know my picture is not great, I took a bunch but for some reason phone did not cooperate!

bringing this topic up as I get ready to work on it on sunday and next week! If anyone has an idea it would be super helpful, otherwise I'll just follow my instinct!
 
The counterweight fits to the underside of the cover so you’re missing the whole thing.

They do turn up secondhand but be careful as there are two types - one with a silver cover and one with a black, and the weights are different. Your 3400 needs the silver one.
