The body appears to be MB/GPW.

“For your consideration is a cleanly & near fully restored 1951 Willys
CJ2A(?)Jeep 4X4. Appropriately nicknamed The Killer Bee (& having 3
hand painted Custom logo), this project began as a repair this, and
make that, and with time gradually ended up becoming essentially a
Top-down Custom Restoration project. With Approximately $14,500
invested, my loss is YOUR GAIN!! For Sale – $7500, obo.

This Willys is being listed for a friend, so reply by phone, NOT by email.
The phone number is shown at the end of this description.

This jeep has been garage stored nearly all the time especially in the
winter. Before restoration, original body rust was very minimal.
This Willys is loaded with custom made parts, and the outer body
and BUCKET interior has NOT been commercially painted having instead
been Coated with Yellow Rhino Coating with Heavy Texture for
providing an extremely durable surface for the most demanding or
abusive conditions. Rhino coating is a virtually indestructible Truck
Line-a-Bed product. Polyurethane based, Low VOC, coated with a very
heavy texture, uncommon for automotive surfaces, but will hide dirt on
this bright color very well. You could throw a wrench, or a full size
long nailed dog could jump on the hood without leaving a mark. This
surface coating is often used on smaller ATVs. For further info click

The expertly custom designed and manufactured black removable
hardtop was made with aluminum sheet-metal & is also Rhino coated
yet the hardtop has an awesome Medium texture. This gorgeous top
includes 2 rectangular rear side windows, and an aesthetically sized
oval rear window & matching removable black coated doors for both
the driver and passenger sides with lockable door handles, and custom
lockable sliding windows. The doors can be installed or removed in
minutes, and are easily stored. The fully handmade custom hardtop
& doors were strategically creased to blend for fit, form & function.
Other custom parts include the cool exterior rear mounted spare tire
bracket fabricated from standard cold rolled steel (CRS)tubing simply
designed 2″ X 2″ CRS rear bumper and painted black. Interior features
include a custom Full cage roll bar, painted black, and nearly fully
covered with matching bright yellow foam padding. The dash board
having standard speedometer, odometer, & fuel gauges is cleanly
lacquered in matching yellow paint. Included are electric windshield
wipers for the original drop down front military windshield. The original
glove box and door remain to maintain originality. Newer electronics
included a Cobra CB radio with electronics integral to the handset.
The super-long CB antenna mounts externally to the passenger side,
and is usually looped to the windshield while cruising around town.
A Marine AM/FM/CD player stereo is installed between & just behind
the front seats. 2 quality speakers are mounted on or near the rear
fender wells. A portable electric heater/defroster is included
which plugs into the spare 12vDC cigarette lighter outlet jack, and is
temporarily mounted to the windshield when necessary during the cold
winter months.
