Uberti is making Win. Highwalls in .45/70 I think. Maybe the 38/55's were in Italian low walls. I'll check.
I know lowwalls came out a while back in up to .243, but that chambering disappeared and left only the Hornet and RF's.

"During the 2005 Remake of the model 1885, they were made in many modern calibres including the .45/70 and .38/55.

In 2005, Winchester reintroduced their famed 1885 Single Shots, labeled the Limited Series. The 21st-century Winchester Single Shot rifles are built with modern technology and steels, enabling them to fire modern smokeless cartridges; the currently popular cartridges of .17 Remington, .243 Winchester and .30-06 Springfield were offered with standard rubber recoil pads and straight butt plates. However, four of those Limited Series Model 1885 SSs were subtitled Traditional Hunters. Those four rifles, in calibers .38-55 and .405 Winchester, .45-70 Government, and .45-90 BPCR, were built in the style of the 19th century, with crescent steel butt plates and 19th-century style folding tang sights, along with full octagon 28-inch-long barrels. Their rifling, in the case of the .38-55, are the (Winchester) traditional one complete turn within eighteen inches (1-18") with rifle grooves at .376, and rifle lands measuring .368 of an inch. The .45-70 is by far the most readily available of these four vintage cartridges. "
