just bought the hobby boss M4 HST late (82408) and just wondering about the louvres on the sides of the ammo boxes at the rear.I get the impression from reading the review on PMMS that these are a feature of the late production run of M4s,however in Steve Zaloga's build of the PSP M4 way back in 2000(i think) there's a pic of the two M4s and it's stated that the louvres were a feature of the initial production run,so...... who's right?i don't have the tankograd or ampersand books so if anyone can enlighten me.
Thanks in advance

Based on what I have seen, the late units had the louvres. These were also used a prime movers for the 8inch and 155mm Long Tom towed weapons.

Rounds Complete!!
