Brief Jeep History


In 1941 Jeep production started for W.W. II.  These were made my Kaiser and later by Willys and Ford. 


Starting September 1950 to 1953 the M38 Jeep was made with a total production of 61,423.
The M38A1 started production in April 1952 and stopped in 1968.  101,488 of the M38A1 were made.


In 1960 the Military Unit Tactical Truck M151 MUTT was introduced.  Over 150,000 were made.


The HHMMWV (Hummer) started in 1984, although it not fair to say it replaced the MUTT all the prior "Jeeps" were 1/4 Ton vehicles and the HHMMWV is a 5 Ton vehicle.

Title Image

In the title image above of an M151 with the VRC-12 VHF low band squad radio setup and the KY-57 communications security device the radio equipment is installed on the road side.  This is not the normal place since with both the driver and the radio on the road side the vehicle is heavy on the left and more prone to tipping over.  For much better balance the radio is normally placed on the curb side.  If an officer would be riding in the vehicle  most of the time then this road side placement is desired so the officer can operate the radio controls.  The long antenna whose base is mounted high up is the AS-1729 used for both transmit and receive.  The shorter antenna is used for the R-442 receiver.

My Interest

My interest in the M151 came about when looking for a vehicle as an accessory to a Squad Radio system that would include the KY-57 communications security device and a PRC-77 radio in a VRC-64 configuration.


M151A2, nice restored condition, no ROPS, with canvas top. 
Best with no radio equipment, but a proper installation on the curb side would be OK.  Let me know what you've got.
This is aimed at making a complete GRC-206 system.
