Hi K3n - I hope this works!
This one of my machines, a 1947 Bebarfald Bluebird, produced in Australia where I live, the machine itself is a Vickers. These were sold as a writing and sewing desk and were considered very topline furniture pieces of their time here. Note the Bluebird of Happiness on the machine. The advertising blurb was a blast, it went something like this, the wife would be happy sewing at home and the husband would be happy because his wife was kept busy and hence the bluebirds to signify that they were both happy. "Queenie" is one of forty machines I have but she is my best piecer for quilting outdoing the modern machines in my collection. Pic is when I first brough her home, she is much prettier now :)
