on the back of Excals catalog it says warranted for a period of 5 yrs from date of purchase. then it goes on to say after that period its warranty at the discretion of Excalsfor the lifetime of original owner. i own a vixen thats 10 yrs old i am willing to bet that if something was to go wrong and i didn't cause it. excal (Dan Miller) will warranty it! only Bow that is #'ed is their Y25 as its only 1000 made. all the rest have no serial # on them.
