...is this part replaceable? My raffle win 66 red eye has a broken lever to lift up/down the presser foot. Not sure if she broke on my trip (I couldn't find it in the trunk so maybe when the bf rearranged the trunk before we went home?? Hmm) or if she was like that when she was submitted. She is worn but still turns. I can still lift the presser foot with the nub but it's sharp (which makes me think it's recently broken) but would like to know my options on fixing it. Is this a part I can find and replace (by hopefully unscrewing and resrewing a new one in? I'm also not opposed to some clever solution like soldering a pretty glass bead on a metal rod to it. While I'd love he to remain stock, her decals are pretty worn anyways and mayb one day will be a candidate for a repaint. So advice is welcome.
