Day 215/22. A 'what is this? test.....

We never quite know what will turn up at the museum. Today a new item appeared. This is the mid upper gun turret from an Avro Lincoln WWII bomber.
The Lincoln was the last piston-engined bomber operated by the Royal Air Force.
Later in the day we had another donation arrive in the form of a WWII print of a Battle of Britain scene. Nothing unusual in that. Except that this print was signed by both Sir Douglas Bader and Adolf Galland......
What will we get next week?
