Hello all,
I've come across a Nauticam flat port 45 with a damaged M67 thread - it doesn't look great, the thread seems quite crushed and mounting anything is not an option, which is a deal breaker.

However I thought I'd ask for your opinion - since this is aluminium and quite soft, does it look like there might be an option to rethread it?

The pictures are not the clearest, but all I have for now.

thanks!

Looks dodgy. One thought though. Some of my diopters included a M67 "spacer" ring. Perhaps something like that could be screwed on with some necessary force and then left in place to mount other items on the good spacer threads?

Perhaps someone has an unused spacer they could donate?
