I have one. It's a Model LT-72 SELECT N SEW.

It's made by Toyota and is an all mechanical, no plastic insides machine. It uses cams and sews very well.
I'm guesstimating it was made in the mid 60s.
I would qualify it as a good but not exceptional machine.
Other than that I really don't know anything about it.
