Well Revell makes the Stuka in 1/32.Airfix has one in 1/24.(This is huge....)Forget Tamiya-like precision part fit on either offering.lot's of work there.Depending on how anal the goal with this,count on rescribing panel lines.Cockpit detail is crude/sketchy.Decals might not be in good shape.
Bright side is they are beautiful when finished and plenty of ref/tweaks and AM support areeasy at hand.
Armorama is good,but also check out Large Scale Planes website.Do a quick google as I don't have address handy.
Have fun
