Hi,
I have purchase an antique piece on ebay and now I have grave doubts about its being antique. It's a tea kettle and the claim is that it was made in the 1800's. However, the pieces are being held together by nuts and bolts. I have (low quality) picture that I took with my camera phone here:

Now I'm sure that the nut has been replaced, but the "bolt" part is actually part of the handle - the threads are on the piece itself. And the threads on the "bolt" part are a modern gauge and thread count. Now, my question is this: can one tell when the contemporary thread sizes were finalized? Was it in the 1800's or was it more like in the
1970's. And by looking at the picture that I provided, can one put a lower bound on the time period in which this piece was made.
Many thanks in advance!
Aaron
