“Jones” is a brand name for knitting machines manufactured by Brother Co. and sold in the UK. The model numbers are interchangeable. So, if you see a model number but under the “Jones” name, look for a Brother machine with the same model name. Some Jones machines, though, resemble those produced by Corona (I suspect Brother bought Corona at some point because some earlier Brother models also look like Corona machines, e.g., Brother KH210).
