The grommets are a genius idea! I'll have to find some and try that.

Does it have space for a switching PCB? I see one switch in the photos- does it have all three?
There is space, but just one hole.

Will it screw onto a Neumann mount?
Just listened to the file the following are some ideas I could be way off not having one of the bodies to test
The following are GUESSES
For the body tube it sounds like the round ends might not have enough pressure at the headbasket and bottom screw on part to end of the tube interfaces.
This could be from the surfaces not matching or the internal rails are too long for the body.
You can try lapping the parts with a lapping compound
OR
using a O rings or DIY gaskets at the interfaces (I would try this first)
The above might also help with the headbasket ringing
EDIT forgot to add, think of how you can damp a wine glass vibration.

The finish is painted or plated?

"McDaddy Microphone"?
Other than that, doesn't look too bad... And on the bright side, it's "made in Germany"...

...Do you happen to know the dimensions of the head basket?

I notice that 'the switch is not functional, only decoration'.
Yes, but I'm only interested in cardioid, (switches can be adapted if needed), it's important that the headbasket is close to the historical one.
Seems to be like this one but with added "switches".

Close to the original, but not spot on.

Order one, and you wil know!
Hi Kingkorg,
Thanks, I followed your recommendations.
It's on its way, I just need to find a way to dampen the unwanted resonance from 100+ Hz.

You are right!
I will actually order one and share the test results.
I contacted the seller on Ali, and got some more info on this new body.
For reference, the body initially mentioned at the beginning of this thread, that is close in size to an actual u87, is called the "HL-77"
This new body, the one that looks more like an 87 body with the cosmetic only switches, is the "HL-95"
These are pics they sent me of the HL-77 and HL-95 side by side, with and without shell, and another close up of the inside of the 95.
The vertical distance between the mounting holes on the rails of the HL-95 is 80mm, which I believe would perfectly accommodate one of Poctop's D87 boards. I've asked for the measurement of the width from hole to hole, whether it's 34mm or 38mm, so I'll report back if I get an answer.

The response was the width between pcb mounting holes is 32mm.
Anyone know if that would work with any of the currently available 87 DIY pcb's out there?
