Boston 1954, Brother has a 1500s machine (some more initials to the model number, can't remember) but it has a 9 inch throat and can do regular sewing and FMQ, straight stith only. It is a fantastic machine, very strong, some describe it as semi industrial. Sells for between $500-$700 or so. I bought one when they first came out, approx 2001, it is still going strong, I FMQ many quilts on it. I think Juki has a similar machine.
