If it's a tea strainer something seems missing that keeps the entire thing from going into the water, the loose tea would float out. (maybe it's a hand held kidney stone strainer...eek!)
First of all, based on the construction, the handle is designed to lift the inverted cup with holes
Not a strainer - just the opposite, flip it over, the holes are meant to be on top, creating a cap of sorts
this looks to be a cap of some sort, for gas flame? A flame diffuser?
I like the idea of a camping item, gas lamp?

When I first saw it my first impression was some type of flame diffuser. I agree with bradyboy.
Also the handle seems to be somewhat long. Possibly to keep the users hand away from a flame??
I agree with bradyboy also. The basket would be up-side-down if the bail was used as a handle. It doesn't look like a handle anyway considering the shape and design. I'm thinking it is a retainer of some sort. The basket would mount on something and the bail would swing over the top of that something and snap in a groove, holding the perforated cup in place....kinda like an old style brake master cylinder lid. As for it's purpose? Filter? Drain?
