Brilliant tool the Sharp Ace and amongst the most accurate rifles in my little collection. I recently had to replace the flimsy bolt plate and got one from John Bowkett. He has quite a few taken off Aces that he did his bolt conversion on in the 1980's. Anything that was any good he never threw away.The pressure relief valve spring from these and the Innova were later used in the first few hundred Titan Manitous as a valve return spring
