Looks to me like the original owner bought the rifle, then decided at a later date to upgrade a bit. I have done the same myself, many times. Rather than buying a new rifle, when he already had a perfectly good one, he bought some accessories, and dressed it up. Upgraded sights, a barrel level, and a shceutzen butt plate, and he turned an already excellent rifle, that he liked, into a real target shooter. As oldstarfire mentioned above, the Winchester Hiwall was an excellent rifle, one of J M Browning's finest, and a true classic. Several manufacturers are building reproductions today, including Browning, Winchester, Pedersoli, to name a few. The 38/55 is probably one of the most popular of the many calibers it was chambered for. I would absolutely clean her up, and give her a try. I had surprising success with an old rusty 1886, in 47/90, using jacketed bullets. If nothing else, there is a very good market for 1885 actions, to rebarrel for the Black Powder Cartridge Rifle (BPCR) market. The action alone is worth at least $900, more with the SST (single set trigger). If you put it on the EE, your phone will ring off the hook (and it will be me on the line). :-D
