1941 - 1945 MB & 1942 - 1945 GPW
The WW2 era Jeep has been and continues to be one of the most sought
after of the vintage Jeep models.  Willys Overland began production of the
MB in 1941.  When Ford came into the contract to help produce the Jeep in
1942, the Jeep was standardized to ensure parts were interchangeable
between the Ford GPW and Willys MB models.
There are some very good books available for more detailed information
regarding the WW2 Jeeps.  The All American Wonder books, Vol. 1 & Vol. 2,
are very good books for those engaged in a restoration.  The Standardized
Wartime Jeep is another good reference.  These and others are available in
our catalog.
1941 "Slat Grill" MB
MB Identifying Characteristics:
Data Plates: there is some variation from year to year in the data plates -
1941 MB data plates were made from brass, the later years were aluminum
Windshield Frame: two piece windshield frame (inner frame and outer
frame) with split glass, round tube construction *Note: CJ2A, MB/GPW, &
CJ3A windshield frames are interchangeable and it is not uncommon to see
this.
Front Bumper Gussets: front bumper mounted to a set of gussets, rather
than directly to frame horns
Frame: front cross-member is a round tube style
GPW Identifying Characteristics:
Data Plates: there is some variation from year to year in the data plates -
1942 GPW plates were made from brass, the later years were aluminum
Ford Script "F": just about everything was stamped with the Ford F -
apparently Henry didn't like warrantying Willys parts!
Frame: front cross-member is a u-channel style (with the exception of
February & early March 1942 GPWs, which had used Willys frames)
Grill: 1941 MB had a "slat" grill with welded vertical bars, the standardized
stamped metal grill came into use in 1942
