Uh oh. Possible one of those fakes "built" by that EBay scammer?

Very suspicious indeed, example the well known eBay seller called "2465b" , the shop is also selling the handle decal for 2465B, example ebay item -> 123714403213
They're printed in single color, as example mine it was printed with dual colours, check the very 1st post of this thread.
Oh gawd... this schizz has infected ANOTHER thread.
These are JUNKED OSCILLOSCOPES. You can't assume anything about them.

Show me anything that in any way ties this guy we all already know about to a busted, scrapped out scope on a trash heap halfway around the world.
THAT is what's wrong with this. It's effing mob mentality, pure & simple. Dave has been notified; that could have been done via PM. All the rest of this is needless sensationalism that makes this place smell more like an episode of COPS than anything resembling reasonable discourse.
There's a whole thread already DEDICATED TO STIRRING UP THE SENSATIONALISM... can we PLEASE just leave it there until we actually KNOW something?

Repost here as reference.
A fellow forum member, mnementh was requesting for a confirmation (HERE), whether 2465B vs 2465 blue outer cases are identical, as he has part mules that planning to donate it related to Dave's at his EEVblog #1203 - 2465B repair video.
While for the back cover, the B version has thicker part at the internal axial fan location, compared to non B that uses a squirrel cage fan instead, I guess its not suitable for replacement, not very sure though.

...Looking at the part numbers in the service manual, the case is part 437-0286-03 for 2465 serial B021870 and up, and also for 2465B serial B050000 to B050740. So, for some period of time it was the same case for both scopes. Looking back at the video, it's a little hard to read, but it looks like Dave's 2465B is B050574.
The rear cover for the 2465 has two part numbers, 200-2685-00 for the squirrel cage fan and 200-2685-01 for the updated axial fan. The 2465B is 200-3200-01. So, Dave will presumably need the rear cover specifically for the 2465B.
(I'll just post here since mnementh reads this thread too.)
Can you inspect the other side of the board? Since your battery is showing as-new voltage, I suspect somebody may have replaced the Keeper pack either after the cal data was already lost, or without providing proper backup power while doing the swap.

Yep, some gorilla has been in there. Now I can't help you with the availability of parts but I can tell you how to get that front panel assembly out.
Remove the Intensity, Focus, Readout, and Scale knobs. Be careful and use heat or else they will crack.
Running along the top edge of the scope is a plastic strip. Carefully pry it up.
There will be screws in there. Remove them. There will also be screws on the bottom. Remove them too. Edit....and on both sides too.
The front bezel will pull off. Once off you can pull the front panel assembly.

That appears to be the answer (see photo) as the battery solder connections look different and less precise than the rest of the board.
From my notes, very likely from this thread somewhere...
