I need manuals for 3 Imperial sewing machines made by Husqvarna-Viking. 2 machines are light green and darker green. The Model number on 1 is 190, Deluxe Zig-Zag. The other gren one is Model 708, which is older in design with the thread tension adjuster on the back side of the head. The 3rd Imperial is done in cream and blue with 13 built in stitches including an automatic 4 stage Button hole maker. This machine is very heavy duty and all 3 machines are portable or table mount with knee or foot pedals.
