I bought this bike from a garage sale about 8 years ago. I recently became interested in knowing its history. Can someone help me identify it? It says "Shogun Hi-Ten 200" on the down tube. 10 speed (2x5), shimano altus parts, dia compe 630 side pull brakes. I removed all the rusty parts and stripped it down to the frame. Here are some pictures. I'm wondering if it's worth getting some parts and building it up for my wife for riding to farmer's market

BTW, the S/N on the bottom braket is M3D17395
