Ruger number 1 help

[jljr1944]

I have a Ruger number 1 in 458 win-mag. The rifle was made in 1976 making it a liberty model. My question concerns the stock. I can not find any rifle like it with the same stock. Is the stock factory or after market. If it is a factory stock does anyone know how many were made with this Monte Carlo stock and approximate value?
Thanks
