I was flying as pilot in command in right seat. An acquaintance; who is a commercial pilot; was flying the aircraft from the left seat. He made me take off and made left traffic for further touch and goes. A good landing (3 point) was then made; flaps were reduced to 10 degrees and take off power applied. The aircraft was straight and on centerline. At approximately 40 MPH IAS; the nose began coming around to the right. The tail wheel was still on the runway. I took control; applied full aft elevator and full left rudder; but the aircraft ground looped to the right; tipping and hitting the left wingtip and left elevator on the grass before returning to an upright position. I secured the aircraft and we exited the aircraft. Upon inspection; we determined the aircraft could be safely started and taxied off the runway. I taxied the aircraft to a maintenance facility on the field. Current weather was approximately 1;500 FT scattered clouds with no clouds above. Wind was calm; visibility was plus 10 miles; and runway was dry.
C170 Instructor reports a ground loop by the pilot flying during a touch and go. The instructor takes control but is unable to prevent the left wing tip and horizontal stabilizer from contacting the ground.
