Yes, they are.  And they are still used in Britain.  I've several that  
I got from my ex-mother-in-law, while I lived in Britain (was married  
to a Brit).  The jars aren't square, but round.  They aren't as easy to  
use as American canning jars and metal rings etc, but they do have one  
superiority.  Acidic foods do not cause them to rust.  In my,  
admittedly limited, experience one of the most popular things canned  
are pickles or chutneys.  Err, not the same as our pickles/pickle  
relish.  Anyway these are quite acidic and need the glass jars and lids  
or now, more modernly, they are put in plastic containers and frozen.
