If its been well cared for it should be better than alot of rifles they sell today. I regularly use 90-70 year old rifles with no problems whatsoever and they are meant to last a considerable time longer than that with care. My shotgun is a 130 years old and works as fine today as it would have a 100 years ago.
True the metal alloy technology wasn't as great as it is today, but steel like that doesn't fatigue with age and they are exceptionally well built buggers designed to hold the high gas pressures of the 30-06, so I say if the price is right its well worth getting for a piece of authentic history of a ww1 rifle thats been past down through the years.
Just do the usual headspace checks, check the barrel and the crown and all the stuff like that which any competent gunsmith will do and you have an excellent rifle. You may send it to me if you really so wish. I promise not to complain.
