Elna Air Electronic TSP model 390B; high quality, made in Switzerland; heavy duty metal. Great condition, with cover, everything needed (foot control, cord, bobbins, oil, various needles and pressure feeders). I'm just not using but it's a fantastic machine. Been carefully stored. On ebay for C$300-500
Here's a video to show basic operation https://www.youtube.com/watch?v=vPbWPNXlu8M&ab_channel=InStitches
