We had the same hinge on our 38FL Fail.
They are not made by Blum, they are similar but a cheaper version.
I replaced my hinges with the Blum hinges, they are better quality than the OEM installed hinge.
Available online at many retailers, think I got mine from Amazon.
Do a online search for for 170 degree cabinet hinges
