What is this?
 

Came across the pieces shown in the pictures below in a box of parts that came with my truck.

The first appears to be some kind of a "T" wrench with a square hole in the end that's about 3/8" square.

The second were two each of the item shown in the second set of pictures.

I haven't a clue as what either of these two are for; any help identifying either will be most appreciated!

Regards,
Jim

My Guess
 

Hey Jim, The T piece looks like a key to fit hatch locks like those on Ferrets, will you take 5 bucks for it? :D

Jim,

The semicircular covers are to protect the head and side lamp wiring on Daimler "Dingo" Scout cars, they bolt under the front mudguards, it more than likely that the T key is for the Daimler engine cover locks. As these locks are the same parts on Ferrets, then Wayne is correct.

and the other item is a red ballpoint pen :D

Wayne and Richard:
Thanks for helping me identify those parts! In the meantime I discovered that the wrench fits the drain plugs located near the water pumps on the engine. And, the red pen is a BIC.....

Regards,
Jim

Odd parts to have
 

The Daimler description fits. Your owner had a Daimler some years ago. Also the key is similar to the drain plug wrenches issued with Carriers. A Ford stock tool.
