Registered Will versus Gift deed

My father's mother (grandmother ) she has self acquired or self earned property of 3 schedules eg a, b,c .My grandmother has 4 four childrens one son that is my (father )and three daughters are also (married). In the year 1997 my grandmother has executed a registered will for Shedule A and B property , schedule A in favour of me(grandson) and B in favour of my father . WILL stating that my Father is only natural guardian for A schedule until I am major(grandson) , he (father )can enjoy the benefits of schedule A property. He cannot sell or take any loan on this schedule A property. Later my grandmother in the year 2000 made another registered Will for schedule C property for her daughters , My grandmother again in the year 2004 she made revocation of WILL (cancellation) that she had made in the year 2000, she has not cancelled the Registered WILL that was made in the year 1997 . Again after revocation of WILL 2000 , she(grandmother) has made gift deed for schedule for A and B property to my father without cancelling the registered WILL of 1997 which was made for me (grandson) . Now my father has taken bank loan for schedule A property and left for the seize of property and bank has come forward for auction. Do I have any rights over the schedule A property on the basis of registered WILL made by my grandmother in the 1997 where it has not cancelled ?
