@Bok: I think the middle one is a 50s pre-F1 pot with a puffed-up lid, but I could be wrong. And I think the last one is probably 80s, but again, others might know more than I do (perhaps
@OCTO, since his hongni one looks very similar to my zini one).
The last one has been used with old puer for so long, that if I posted a photo of the inside and asked "Real or fake?", most people would probably tell me that it's been adulterated with shoe polish and that I should throw it away...
I guess that people making these teapots during F1 times probably never thought that we'd be carefully analysing and arguing about the different shapes, the type of clay, the tiny differences in seals, and the exact date ranges of the pots so many years after they were made.
I do look forward to seeing more pots getting posted onto this page, though. It's fun to learn from these photos.
