FROM: Ford Motor Company, Detroit Office
February 20, 1919
General Letter No. 347
Kindly note general information and changes to date:
As closed bodies are now being painted black, instead of green as heretofore, also carmine striped, it becomes imperative that the branches prepare to repair bodies when needed according to the new color. It is necessary that someone in your paint shop, accustomed to the method of striping, be assigned to this work, as this section of body painting is something new for branches to contend with. Striping pencils and carmine paint for striping will be furnished to you for this purpose upon receipt of request for same.

These are being sent you at this time and comprise the change in sedan, coupe, touring car and torpedo body painting, according to the latest information. You will note the change in the Symbol number of paint used in painting closed bodies, as well as that for touring car and torpedo bodies, and wheel paint, as called to your attention in our general letters of the 11th and 12th. F-165 and F-166 will be held for repairs only on closed bodies which were formerly painted green.
Attached is the new brush list comprising changes to date of February 20th. Have added the number required per thousand cars, and it is decided that branches should order material on this basis. No material should be ordered locally as the main plant can supply your needs at any time.
One length of board is being furnished for sedans, both Wadsworth and Fisher made, and as the Wadsworth body is somewhat wider between pillars at instrument board section than the Fisher body, it becomes necessary for various reasons that one length be furnished for both jobs and when branch receives same it will be in order to cut off ends of the board to fit Fisher body if Fisher bodies are being received. After cutting the boards to size, see that the imitation leather is again placed over ends of boards in a workmanlike manner. Instruments will be shipped to branch from main plant with instrument boards until the body manufacturers can bring the instrument boards through to fit their respective bodies, after which they will ship bodies with the instruments and wiring fastened thereto so that same can be fastened to dash assembly in accordance with diagrams which you have at this time. Coupe bodies are now going forward with the instrument board in position.
This material is intended for striping closed bodies when making repairs and can be ordered from main plant upon requisition.

"The Model TT design will be assembled beneath the axle, instead of above the axle through the spring perch as heretofore.
"Although it would be possible to use the Model T design on the Model TT, we request this be resorted to only in case of a shortage serious enough to threaten loss of production."


APR 14 Acc. 78, #385, Ford Archives
New radius rod used at first on the TT chassis. Roller bearings at first on the TT and on the closed cars.

"The spare rim carrier and method of mounting have been redesigned. On the first 10,000, a forging bracket fastened to rear spring clips, is used. After first 10,000 a steel stamping design of carrier will be made and attached to the frame with three bolts and nuts on each side of brackets. It will be necessary for branches to drill holes for attaching brackets until such time as the manufacturers are in a position to incorporate this change in production. This revision is essential in order to mount brackets without removing the body. All frames are to be drilled if not equipped with a carrier, according to attached print, so that the car can be supplied with same when stock arrives."
