This is actually a parts gun. I selected it out of a barrel full of them in a gunshop in California. It came in a ratty pistol grip stock. The stock on it now I picked up at Rock Island Arsenal when I was attending the National Match Weapons Maintenance Course. It has a slightly counterbored barrel. I understand that in the 50s Army Ordnance had a rebuild program for the Nationalist Chinese on Taiwan. They found that many of the Springfield barrels were actually in good shape except for the muzzel crown where overenthusiastic Chinese soldires had damaged them with improper cleaning. The sollution was to simply couterbore the barrel slightly instead of rebarreling. This one is a great shooter.
The barrel is marked SA 11-26.
