I recently won as the only bidder on an auction for this vintage Marlin scope on Fleabay. It also measures exactly 11.5 inches!
Obviously the scope rings and mounts are all wrong, and the knobs are slightly different, but what do you guys think about the shape of the scope itself? Below is my scope plus a comparison pic someone (not sure who) posted recently.
If it's not dead-on, I think it's at least a darn good $15 substitute
