(Please read the condition of this item before bidding.) This is a group of three different related motorcycle electrical wiring diagrams from Lucas. Each diagram is printed on one page, printed in England, and is undated but appears to be early/mid 1930s vintage. Included are the following: (1) "Special Instructions For The Lucas 4-Cylinder Ignition Equipment As Fitted To The Ariel Square 'Four'," measures 5 1/2" x 8 1/4"; (2) "Lucas 'Magdyno' Or Separate Dynamo Lighting Equipment As Fitted To Motor-Cycles," measures 10" x 12"; and (3) "Lucas 'Magdyno' Lighting & Ignition Equipment As Fitted To Ariel 'Fleet' Three-Wheeler Vans," measures 10" x 12". Condition: All pages: The three pages are attached together in the upper left corner; and pages have multiple folds and a little edge wear. Other condition defects: Diagram # 2 has a 5/8" vertical tear along a fold line in the top edge, and two small round tears along a fold line. Diagram # 3 has a 1 5/8" vertical tear along a fold line in the top edge, a 3/4" horizontal tear along a fold line in the left edge, and two small holes along a fold line.
