Neumann u47fet mounting bracket question

Hi all!

I was just wondering if anyone have purchased or knows where to source a copy or something at a decent price for building a clone of the u47fet body.
I’ve seen that sennheisser sells Neumann tlm107 holding brackets that are similar but for 300£ It's out of my budget.

thanks.

Edit: Bock ifet and Soundelux ifet use that type arm bracket too
