Hi,
Yesterday during lunch time I managed to do a quick repair on a friends reproducer.
As found, it had THAT needle screw and believe it or not it had the thread stripped.

So I had two options, or go one step bigger... or repair it.

To repair it, its important to fill the
hole cavern with the same kind of metal. In this case a brass thumb screw I had around was used.

Then it was sawn and filed flush.

To make the fix stronger, a small drop of flux and tin was needed.

Once heated, it fills the gap by capillarity. After filing the tin the repair is invisible.

The owner wanted a long screw and be able to use soft tone needles (thin needles). This reproducer had a triangular needle hole for bamboo needles so I displaced the screw hole a tiiiiiny bit to the left to allow the screw to reach the corner properly.

Then the needle screw hole was tapped and a subtle touch with diluted paint made the repair to blend with the patina.

And voila! Ready for another 100 years.
