Searching parts for FWB 65/80

[Hawk-i]

Hi, I've searched previous posts here and found from 2019 a website link to the following German business that previous posters have dealt with successfully.

Has anyone here been in contact recently with this business ? I have tried connecting and getting a Header message: business closed until further notice for family reason.
However I can't seem to determine since when has the message been in effect. So wondering if it is 'going to go out of business' if it has been closed from many months now?

My goal is to locate a small spare part for the Rear Sight on a Feinwerkbau 65. I have the correct P/N for reference.
I've searched directly FWB as well as FOEST.Europa and also Waffen.gotha after checking with the only authorized service centre in Canada. All in vain.

Appreciate any leads or suggestions. Many thanks.
