I’ve recently discovered that many vintage cycle enthusiasts also have an obsession with vintage sewing machines: )
My favourites are the Singer 400 series Slant-o-matics from late 50s to early 60s. High tech in the day & very expensive. All gear driven, with cast alloy body they still perform reliably, with cam driven stitch variations. No electronics, no plastic ‘gears’ & slippery belts that appeared later when cost cutting accountants had their way.
Here’s some pics of my 411M (M= Monza?Milano made) which is regarded as the ‘Holy Grail’ by many.
Rightly so, because it not only provides multiple stitch variations, as do the 401G, 401A, etc. but also chain-stitch. Still rare on any domestic machine.
Plus a couple of other very nice, early machines. A Pfaff Model B from 1897, Fristers from 1896/7 & 1907.
More recently an Alfa 50 which cost £1:04 off ebay: )
