TahoeKiter

A gentleman came into our store the other day and sold us 5 kites he had for many years. The only reference I have is the assembly sheet refering to the name "SL 88" or "Airforce Power". There's two sizes, 7ft (1748 sq ft) and 9 ft wing span. They seem pretty well made and appear to be very durable. Actually they are very heavy duty, but it says the wind range is 5-45 MPH. They have two horizontal cross spars, and two verticle spars, 5 standoffs and has a "V" cut at the nose. Only two of them had line and bridles that connected to a PVC bar. I'm looking for information on it's origin and set up. Any help appriciated. Thanks David
