Handheld mechanical tachometer. Nice old bit of kit that still works well, though I did have to straighten out a bend in the needle which was presumably caused by someone attempting to use it on too low a range. Dismantling was initially required to find why it wouldn't go back to zero. Whoever damaged it, didn't have the decency to tell anyone it needed repaired.

First Chiffchaff of the year heard singing in the Manse Plantation area whilst cycling to work this morning.
