First post, need help on a Winchester 5640289

[DaveHH]

They were using both as available. You will also sometimes see the oil hole in front of the trigger left side Trigger housings. The sight, if original to the carbine, will have a round punch mark on the right side slots front and rear and no indication of staking for a flip sight. I seriously doubt that a Rockola barrel was ever used on a factory built Win. Jim is correct (as usual) about the price, people get excited about Winchesters and are willing to pay. There are quite a few of these 5.6 and 5.7s in original configuration out and about as they were overlooked because the adjustable sight was mistaken for a rebuild.
