I found an old ad on E-Bay from 1924.  It read "U S Army Krag Carbines.  Fitted with new Model 1898 stocks.  The barrels, actions and other parts are either new or have been refinished by the government and equal to new".  They sold for $15.  Sporting rifles were $14. The is a possibiltiy for mine.  I guess no one will ever know.
