With 37mm AA and two .50 cal machine guns.
Too my knowledge, there is no 1/35 styrene kit of the M15. BUT… there is a Commanders Models M15 conversion for the Dragon M16 kit. The conversion is a little pricey, $64.95 US, plus the cost of the M16 kit which can really cost more than the conversion.
But here is a link to the conversion. Hope this helps.
Somewhere in Ohio
I was looking at their kits and conversions. Lots of cool subjects. Definitely a maybe.
