Fair enough - I was more concerned with the armor of the scout vs 'combat' model. I figure the MGs are the standard type Rng 20" Pow +1 RoF 3. Maybe armor -1 for the scout perhaps. Also a possible -1 to hit (like moving Rough Rider).
One thing I don't like about the model is the location and short height of the funnels. In their present location they'd smoke out the bridge and main gun viewfinders if the wind was from astern. If I was building it I'd use one funnel and relocate it to the higher platform just behind the bridge. For 2 funnels I'd build a structure underneath them to raise them far enough that the tops of the funnels are just above the bridge roof.
