I woud not say this is a parts gun. This if from standard catalog of firearms 2009. It's a bit of a read, but here goes.
Model 1886
Based on a John Browning patent, the Model 1886 was one of the finest and strongest lever-actions ever utilized in a Winchester rifle. Winchester introduced the Model 1886 in order to take advantage of the more powerful centerfire cartridges of the time.
Model 1886 rifles and carbines were furnished with walnut stocks, case hardened frames, and blued barrels and magazine tubes. In 1901 Winchester discontinued the use of case hardened frames on all its rifles and used blued frames instead. For this reason, case hardened Model 1886 rifles will bring a premium. Winchester provided a large selection of extra cost options on the Model 1886, and for rifles with these options, a separate valuation should be made by a reliable source. The Model 1886 was produced from 1886 to 1935 with about 160,000 in production.
The rifle was available in 10 different chambers: .45-70 U.S. Government, .50-110 Express, .45-90 W.C.F., .40-70 W.C. F., .40-82 W.C.F., .38-70 W.C. F., .40-65 W.C.F., .50-100-450, .38-56 W.C.F., .33 W.C. F.
The most popular caliber was the .45-70 Government. Prices of the Model 1886 are influenced by caliber, with the larger calibers bringing a premium. The 1886 was available in several different configurations.
1. Sporting Rifle, 26", round, octagon, or half-octagon barrel, full or half magazine and straight-grip stock with plain forearm.
2. Fancy Sporting Rifle, 26", round or octagon barrel, full or half magazine and fancy checkered walnut pistol-grip stock with checkered forearm.
3. Takedown Rifle, 24" round barrel, full or half magazine with straight-grip stock fitted with shotgun rubber buttplate and plain forearm.
4. Extra Lightweight Takedown Rifle, 22" round barrel, full or half magazine with straight-grip stock fitted with shotgun rubber buttplate and plain forearm.
5. Extra Lightweight Rifle, 22" round barrel, full or half magazine with straight-grip stock fitted with a shotgun rubber butt-plate and plain forearm.
6. Carbine, 22" round barrel, full or half magazine, with straight-grip stock and plain forearm.
7. Musket, 30" round barrel, musket-style forearm with one barrel band. Military-style sights. About 350 Model 1886 Muskets were produced.
Yours is clearly a number 1, sporting rifle. notice that it may have only had a half mag to begin with. Given what you've said about the condition of the bore, etc, it would probably be considered FAIR
GOOD
Small repairs, alterations, or non-factory additions are sometimes encountered in this class. Factory replacement parts are permitted. The overall working condition of the firearm must be good as well as safe. The bore may exhibit wear or some corrosion, especially in antique arms. Antique firearms may be included in this category if their metal and wood finish is at least 50 percent original factory finish.
FAIR:
Doesn't have to be working condition, but if it is it must be safe to shoot (modern firearms MUST function, antiques do not have to). There must be at least a tiny bit of original finish or blue or old (antique?) refinish remaining. Non original parts and repairs, alterations, nonfactory additions, and recent refinishing would all place a firearm in this classification.
POOR
For antique firearms, this means rut and pitting, no finish left, and in non working condition with broken or missing parts.
NOW the FUN part:
Exc. V.G. Good Fair Poor
15000 10000 7500 5000 2500
Looks like you might be getting a pair of sakos instead of a savage

Good luck.
