[Lynn Eades]

I have a copy of the (common?)blue covered 1940 to 1942 book which on page 66 lists 2 more options, and on pages 68 and 69 lists 2 conversion kits "Used to convert vehicles in the field, from truck type steering to the larger bus type steering". There is also a kit to raise the CO1QF steering by one inch.
I believe some models of these steering boxes would have been made by Gemmer engineering, as they have close similarities with the Gemmer boxes found in 3/4 ton WC series Dodges of the same era.
