One of the things I love about the hobby is learning the history behind the vehicle I’m building. I’ve accumulated a rather large library on almost every possible modeling subject you can think of. I’ve picked up four references for the M-10. The first two are by Steve Zaloga; one of the best armor builders out there, and a prolific author of great model reference books. I picked them up pretty cheep ($9 each) at www.overstock.com. One of his latest books “Modeling US Army Tank Destroyers of World War II,” is a gem, full of lots of great modeling tips. He has a build of the Extratech M10 Achilles in the book. It’s basically the same kit as the one I’m building, but it has the British 17pdr and late style turret with duckbill counterweights. The other two books are more photo references of the M-10, with only a minimum of text.
