Spare part for Ikea lamp Lerdal wanted

I hope someone can help me. So... I bought the Lerdal lamp through classifieds of a major online auction house :D. I wanted the lamp already a few years ago, but somehow I missed the opportunity and it hasn’t been available at Ikea for quite some time. At first, great joy. However, we had to find out that one of the rings (the ones you screw on where the light bulb is), which hold these glass parts in place, is broken and doesn’t really hold anymore. Ordering via IKEA online didn’t work because I don’t have a part number. Do you have any alternative ideas? Just going to IKEA is bad, the next store is about 60 km away. I am grateful for any idea.

Hello,

just go to an electronics store with such a ring, they should be able to help you. I assume that it is a standard socket for G9 bases with a screw ring.
