It's rare to see the later Thorn Escorts, but saying that the older ones are practically non existent these days.

I recently got one of these from eBay. That one seems to be standing up the weather relatively well.

@Andy: I not seen the older versions but I bet they look amazing @Oliver: Yes seeing your post on here helped me recognise that fixture and yep it does seem to be holding up just fine even though being in Reading, it sees a lot less rainfall on average compared to other places

Here is the old version Basically a typical oblong 8W fluorescent bulkhead, similar in design to the emergency lights of its era.
