Singer 247 Sewing Machine

Singer sewing machine 247 zig zag and straight stitch. Always stored in a carrying case in great condition. I just cleaned, delinted, and oiled this machine. Runs great, sounds great. Pulls fabric forward and back, timing is on track. Everything is great about this machine and ready for a new home. There are two to choose from of this particular model. Asking $90 or best offer. A or B? Carrying cases sold separately for $40. I also have other sewing machines available come check them out in Port Coquitlam.
