In 1942 a British project for a 3.75 inch (95mm) howitzer began. Two guns were made, one of which was test mounted on a Harry Hopkins tankchassis. Like the Harry Hopkins, the Alecto had skid steering, which operated by bowing the tracks through lateral movements of the central road wheels. The gun was mounted in an open-topped structure. The first trials were not started until late in 1944 and they uncovered various problems. By the time these were resolved the war in Europe was over and the project was ended so very little original material exists for the Alecto. This Restricted Handbook is a RARE example of such material. Published in June 1945 to the instructions of The Chief Inspector of Fighting Vehicles, it contains a wealth of detailed information, including 123 figures that appear mostly as plates, some of which are folding and/or partly coloured. There is also a large folding Table of Lubricants, with diagrams, which came tucked into a front pocket of the folder. Together with this Handbook is sold Data for Alecto I which was issued on 11th, June, 1945 and is Copy No. 14. It contains drawings on the following Tank Data : Outline. Plate Thickness. Engine & Transmission. Suspension. Track Lines. Transport Diagram. These come under the first heading ‘Drawings’ on the Index page and below this are further section headings for ‘Stowage Sketches’, ‘Stowage List’ and ‘Electrical List." There is a gap after each, presumably for inclusion of material at a later date that never came owing to the conclusion of the Alecto project and in the preceding page headed ‘Notes on Data,’ it states "Where blank spaces are found it should be noted that on the date of issue there is no reliable authoritative information." Two RARE, contemporary items on the Alecto self-propelled gun.
