Hi Southernhunter,
The Tenpoint Pro Fusion came out in 2008. If you get the serial# it will help you if you want to contact Tenpoint with any questions about it. Also, does it come with the Acudraw or Acudraw 50. You might have someone that works on crossbows to check it and see if it needs new strings and cables and draw string on the Acudraw. Tenpoints customer service is great and someone there would be glad to help you with any questions.
Tenpoint's are awesome crossbow, good luck
David
