Wood Embroidery Hoop

Let me start with I am new to embroidery.

I have a wood embroidery hoop that is 12" x 17" with a solid aluminum bar. Does anyone know how this attaches to a toyota AD860? The hoop came with the machine and no manner of attaching. I have attached a picture of the hoop.

Do you know what kind of machine it goes to? Also I am looking for a hoop this big for my toyota.

THank you very much for your help.

they still sell the hoops at toyotaembparts.com
however, you will also have to buy the jacket back holder to go with it. also sold there.
the holder is $149.95 and the hoop is $89.70

Thanks, I looked at the part and now need to look at my machine for the attachment points. I am still learning everyday.
