The M-4 pedestal machine gun mount, as mounted in the M151-series vehicles, consists of the upright post that is bolted to a single-piece bracket that resembles an inverted "U" that is squared-off. This piece was approximately 10-12 inches high and 8-10 inches across. The post bolted to the flat top of this piece. The two trail legs or braces are replicated nicely on the model, even adding the small handle that served to tighten the top portion of the post to the main upright.

Regarding the tow pintle bracket: The M151 and M151A1 vehicles used tow shackles that were mounted under the rear "bumperettes". These were the same shackles as were mounted on all of the series front bumpers, and the rear ones were for hooking the trailer chains to when towing the 1/4 ton M416 trailers. With the M151A2, the plate with two holes that is portrayed on the Tamiya and Academy models is correct.

I live in the LA area, would be great to have the chance to meet the creator of some very fine models.
