Wired part of kitchen heat alarm (Addiscombe CR0)

This might appeal to an electrician but it’s quite a niche item. We had to repair our kitchen heat alarm when the detachable bottom part broke but we had to buy the whole alarm. This means we have half the alarm to give away. It’s brand new (we didn’t change our original wired section as it was too fiddly). This is the bit that gets wired in and fixed to the ceiling. You need to acquire or already have, the bottom part with the battery to actually make it work. But maybe an electrician or handy person can make use of this. It’s made by AICO, type Ei144. See photos. Collection anytime from CR0 7JR.
