Speedos and Gauges (Under Re-Construction 9th Aug 2014) I
have done much research on speedometers and gauges used in the Ford GPW
and Willys MB jeeps. There were five brands
of speedometer used. These are AutoLite, Motometer,
King Seeley, Stewart Warner and Early
speedometers had a long needle which were
superseded by speedometers with a short needle in Jan – Feb 1943. The
short needle has a half moon shaped counter balance. The AutoLite
speedometer is different to the other brands as it has a 5 mph
incremented dial only with no 1 mph increments. It also had luminous
paint on the needle only. The other four had 1 mph incremented dials
with the 10 and 20 mph markers having luminous paint on them along with
the needle. Two
brands of gauges were used. These are AutoLite
and Stewart Warner. Early AutoLite fuel
gauges were actually marked GAS at the bottom of the face until around
March 1942 and from then on were marked FUEL. Early
Stewart Warner gauges had a different bezel to the later ones and are
commonly known as paint can lid gauges. These paint can lid gauges were
only used till March 1942. AutoLite
gauges were used in the Mb with Stewart Warner gauges being used in the GPW.
There are variations in the gauges from early to late which will be
explained in the correct gauges for the Mb and GPW
jeeps. AutoLite
gauges have no manufacturers markings or name
on them where Stewart Warner gauges have the manufacturers name printed
at the bottom of the face with the exception of Amp gauges which have a
block F only till around April 44 when the manufacturers name was
printed at the bottom of the face. To

The face style number printed at the top edge of the face is 403261. The model number is printed on the back of the case along with the date of manufacture code. The model number is 590 AD and the date code is a letter and number printed after that. The letter is the year and the number is the month. 590 AD K4 is 1942 April 590 AD L10 is 1943 October 590 AD M9 is 1944 September 590 AD N12 is 1945 December KING SEELEY
There are three types of K-S speedometers. The first type has a 65 mph face with the model No. KS-40363 BN printed at the top and can have either a long or short needle.
The second type has a 60 mph face with the model No. KS-40363-C printed at the top and either a long or short needle.
The third type also has 60 mph face with the model No. KS-40363-N printed at the top. All three speedometers have white numbers on black wheels and all number fonts are the same. The early type has the long needle. The mid type can have either the long needle or the short half moon needle. The late type has the half moon needle. The late type also has a different case to the other two. The case shape is the same but it has a screw on plate added to the back of it. Fuel Gauges Three types of fuel gauges were used. The first is a paint can bezel and the other two are identical except for the needle. During 1942 a long straight needle was used which was square cut at the end. From 1943 onwards the needle was shorter with a slightly rounded end. All have Stewart Warner made in U.S.A. printed around the bottom edge of the face. Amperes Gauges
The amperes gauge is a 50-25-50 gauge with a long, straight, square end needle. It has a block F printed at the bottom of the face or Stewart Warner made in U.S.A Oil Gauges
The oil gauge is a 0 to 80 Psi gauge and has Stewart Warner made in U.S.A printed around the bottom edge of the face. Temperature Gauges
The temperature gauge is a 100 to 220 Deg. Gauge and has Stewart Warner made in U.S.A printed around the bottom edge of the face. It also has a flat steel binding around the capillary tube.
