This is an excellent build, Sam! I've done this model, and I am VERY impressed with the mods you've done on this.
Not only did the duckbills turn out great, but I am loving how you re-did the turret rear walls to make them vertical, a detail many would have completely missed.
Tamiya's M10 is one of my favorite kits, and I love how this is going.
Great great work, my friend. Stick with it, it'll be a winner for sure.
Cheers, from a very impressed, Pat
