The one pictured in "Meet the Sniper". I haven't seen it in game, and I'm not sure but I don't think it's part of the Sniper asset Valve released a while ago. A guy I know is planning to model it for use later. What I'm wondering is, will his modeling be worth the effort or is there already a model out there? I thought that since a lot of you are rather good mappers, you might have a better knowledge of this than me.
