I collected my new, old machine today. Some pictures are in the gallery.
It involved a 4 hour round trip, but it was well worth it to avoid the perils of delivery vans. I'm delighted with it! There hasn't been much time today to get to know it, but I have had it running. Straight stitch and zigzag are good, balanced stitches and the stitch length regulator is working. It has the original Bakelite (?) foot pedal, the rectangular block type with a button and a toe rest, but the capacitors have been removed by the seller to avoid phantom sewing. As I learnt to sew on this type of foot pedal it seems familiar, so I probably won't bother replacing it. It's in great condition for its age. The only visible mark is one scratch on the case and the only other shortcoming I've found so far is that there is only one bobbin with the machine. Oh, and the selector knob is a bit stiff, probably due to lack of use. The drawer set and extension table are present and correct. Feet include general purpose, straight stitch, zipper, ruffler, binding, button, and rolled hem. There are 5 cams in total. Even the handbook is in good condition.
The old Singer 163 Capri will be going on Gumtree later this week and the 401g will become my back-up machine. I'll start it off with some curtains soon. The faster speed compared to my Janome will be good for that job.
I'm very happy and feel lucky to get such a good example.
