Bullet or not Last night

[spudnuts11]

Found these in my yard last night.
The items in Question are the Key and the bullet like thing.
has anyone ever seen markings on a key like this one?
The brass bullet like object is tooled in the middle as to get a grip on it to twist it?
And has a 1mm pinhole in the tip.

Thanks for your help

I think it is a spray nozzle. Commonly used in handheld pump sprayers mainly for agricultural and pesticide sprays. If it is threaded on the inside pretty certain.

Not too shabby! More then I found in my yard and my house was built in the early 40s. I figured for sure at least one silver coin but nope.
