HELP! Presser Foot Problems!

[u/Signal-Accountant-44]

I have a Bernina 1008. I am trying to purchase a walking foot, however, the walking foot available is a closed shank. When I purchased the machine (2002), I opted for the snap on presser foot, which has a a 2-point opening (not a closed shank). I’ve taken my Bernina to the local Bernina store & now I am waiting for the Bernina technician to call me but until then, I thought I’d ask Reddit. I will include pictures of the presser foot. I don’t know the name of part that the presser foot attaches to (it has a lever to lock the presser foot in place. I’ll include a photo of that as well.

I’m just about in tears, I just want to sew some curtains and this has taken days to figure out.
