Hello hammerback, I love these history lessons. Tremendous wisdom on this site. For info only: In discussing Selous Grips (with the niece of the late Mr. R.Rodda) it was common for African Hunters to order this option for wood-cracking protection, proportably due to the high humidity/temperatures and constant wet/rainy seasons in Africa. Therefore, it is probable that your rifle was made or modified for use in Africa. Best Regards, Wes.
