.Thread guide 5 & 4 series sewing machines B55

It works great to keep the thread in the first thread guide. I have recommended this item to all of my friends who have a 4 or 5 series machine.

It broke when I tried to install it. So no clue whether it works or not. Wish it did because would be so helpful. Maybe its too generic? didn't seem to fit at all on my special edition 480. :-(

This attached easily and is a great accessory to guide thread.
