Replacement spring mech (03/03) UNQUE 27-D-40

A quick learner from Zeeland, Michigan says:
My balance is stamped "(03/03) UNIQUE 27-D-40" . It actually measures 28" long. The channel is 1 1/4 wide for the shoe. Do you carry replacement parts for this?

Thank you for posting, Fred! Unfortunately, I'm having trouble match your balance to any of our Series. Were there plastic attachments at either end of your balance? If so, we will need to see pictures of them in order to accurately identify it.

Here is a picture of the ends.

Thank you for the additional picture. It appears that you will need a custom Series 770 channel balance. To start, please fill out this Custom Balance Order Form. One of our representatives will be in contact with you shortly thereafter.

I have the same device described above at 28" long. There is a single screw attachment at the top. Do you know if the 770 series worked for others?
