Is this tin or am I crazy ?

It weighs only 165 g - that's 5.8oz.
Handle is 8", bowl 7" across top, 4 1/2" across bottom, about 3" tall.
Clearly, the handle is soldered. Maybe a punched steel grid on the bottom.
But - I cannot find a seam on the bowl part. Or any marking. Shouldn't there be a seam?
The handle seam is obvious.
What's with the drab deep olive green paint still so intact ?
This was way at the back of a farm pantry cupboard that never got opened.
I know it's just a strictly utilitarian thing, but it has its own charm for me. It was the lack of a seam that got me looking closely.

 

Looks like steel formed on a "lathe" type machine.

The rust and a magnet say it's steel

 

You do know it is a sieve from the late 1800s - early 1900s.

I always forget the magnet thing ! Yes it stuck well !

 

Yes, actually I did know that, but I've had it in my mind it was tin until I got it out and took a good look. I was expecting to find a seam& it is so light in the hand !
Thanks all !

 

looks home made
