This is a 30-06. The bolt has a hole running up thru the bottom as hollowed out. The barrel has no markings that I can see. It looks to have been reblued. Is this really a Winny. I can't seem to find any information on it. Serial number is 1729xx. The receiver has US on the top. The next line under it says, Model of 1917. The third line says Winchester. Can anybody help me out on this. Thank You, Jeff

Not sure what you are asking. Pictures are always required when evaluating a C&R rifle as many have been modified by BUBBA in any manner known to man.

Winchester was one of three manufacturers of the U.S. Rifle Model 1917. All were in .30-06 vs. the ones made for the Brits in .303 and not marked as U.S. Rifle. The barrel should have the manufacturer and date - this is not the rifles date but rather the date of the barrel, but should be contemporary to the receiver if to be considered "original" vs. replacement. The date of the rifle is established by the serial number on the receiver. Production lists by date do exist. Additionally virtually all parts of the rifle were marked by the maker, however, due to the fact that virtually every WWI vintage rifle was armory rebuilt at least once, mixed parts are the norm.

Post pics - multiple close-ups - if you can and will try to provide additional evaluation.

Besides what lion told you, yes, it is really a Winchester. The other makers were Remington, and Eddystone, which was owned and operated by Remington. We had these made because we did not have enough 1903 Springfields to deploy to WW1 and those factories were already in production of the Pattern 14 Enfield, in 303, for the British. We had it modified to take the 30-06, and it was the most common (and arguably best) AEF rifle.
