A friend of mine bought a .22 Cal rifle last night at an auction in Pa. It was billed as a Remington 1903 .22 Trainer. I looked through all of my books and can not find a Remington 1903 Trainer listed anywhere. Yes, I am well aware of the M1922's made by Springfield Armory, but have never seen one by Remington. Am I missing something or is this possibly one that someone made up out of spare parts?
