Frame brackets for M31C machine gun mount (set of 2)

Chassis brackets for support leg attachment

Set of two steel brackets (left and right) for mounting the M31C machine gun column to the chassis. These brackets are welded to the outside of the chassis and form the attachment points for the three support legs of the M31C pedestal mount, allowing the load from the machine gun to be transferred through the chassis rather than through the body floor.

Material

Steel, pressed

Finish

Plain or to be painted

Application

M31C machine gun mount

Set contents

2 pieces (left + right)

Features

  • Set of 2 chassis brackets for M31C pedestal mount
  • Welded to the outside of the frame
  • Attachment points for the support legs of the M31C column
  • Prevents overloading of the body floor
  • Reproduction to original specifications

★ Essential component for correct installation of the M31C machine gun column. These frame brackets ensure that the weapon load and recoil are absorbed through the chassis, as intended in the original design.

Application

For mounting the M31C Pedestal Truck Mount on Willys MB, Ford GPW and M38 jeeps. The M31C was introduced in March 1945 as an improved version of the M31, specifically designed for the heavier.50 cal M2 machine gun. The support leg construction with frame brackets prevents damage to the body floor.

Installation notes

The two brackets must be welded to the outside of the chassis at the prescribed positions (according to TM9-224 or jeepdraw blueprints). After welding, the three support legs of the M31C column are bolted to these brackets. Note: welding position is critical for correct fit of the support legs.

Compatibility

Specifically for M31C pedestal mount (not for M31 or M24 mount). Fits Willys MB, Ford GPW and M38 jeeps. Not compatible with earlier machine gun mounts without support legs. The M31C was only produced from March 1945 onwards and is therefore technically incorrect for early-war vehicles.

Historical context

The M31C Pedestal Truck Mount was standardised in March 1945 as an improved version of the M31. The main modification was the improved cradle-and-pintle assembly (E10014) and the mandatory support leg system, which absorbed the heavy recoil of the.50 cal M2 machine gun through the chassis.
