You'd have more luck looking at where it is located in the circuit than posting a picture a of brown brick with contacts either end. Its fairly chunky so sure it could be a ferrite of some kind (but they are normally black) or indeed a Fuse, self re

We used to see that a lot with securicor before DHL bought them. They used to tape up the boxes again with brown tape & pretend nothing had happened. We even had tire marks on one box.

We saw this one time when we were trying to develop some lead-free product. It ended up being copper migration. Some of the pads had a brown discoloration and those that did would not wet very well. Your elemental analysis would have shown if ther
