To: OD Order No.: Customer's No.: X426 Re: Attached One foot difference in a wheel base like ours makes about 4ft difference in lock-circle diameter. The side Steering tube prevents our getting a smaller R.H. Circle. The fol. are some figures. [Table Start] Row 1: ① 142" (11'-10") wheelbase no slipper drive | Radii turning Circle: 23'-6" | Diam. turning Circle: 47'-0" Row 2: ② 143 1/2" (11'-11 1/2") wheelbase slipper drive | Radii turning Circle: 23'-11" | Diam. turning Circle: 47'-10" Row 3: ③ A car similar to ② but of 131 1/2" wheel base i.e, 1ft. less | Radii turning Circle: 21'-11" | Diam. turning Circle: 43'-10" (corrected to 42'-10") [Table End] L.H. Turning circle diameters are about 3ft-0ins less than above diameters. Signed: R D Speinier This Sheet must be filed on completion of the work. | ||
