Sheilz, Your Singer 128, White FW and your Singer 66 Red Eye are absolutely beautiful. As far as the spool pin is concerned, Sew Classic has them for an inexpensive price, available online at sew_classic.com! I think you'd be able to get them very reasonable (about $ .65 each) plus shipping, etc. That's a good price! They're tap-in! The decals on your 128 and 66 are absolutely pristine! Wonderful!
