Are you asking what just the barrel sights are or are you wanting the tang sights also?

Thanks, but pics don't tell me what the sights are and who the manufacturer is and yes both the front and rear sights. I know for a fact that a regular manufactured Hi Wall didn't have apparently globe front sights or tang rear unless special ordered.

Uechi,

There were some fairly standardized model front and rear dovetail sporting rifle sights available, but the specifics as to front sight height etc depended on your 1885s barrel configuration and calibre. 

What have you got?

If you went into a gunshop and picked your highwall up off the shelf, these are the standard dovetail sights supplied by WRA that you would most like encounter: 

Front sight: most common is the 21A without the set screw, or less likely the 79D Rocky Mountain front sight

Rear sight for barrels no larger than a #3 weight: 22A Sporting Rear sight (the flat top - not a clover leaf or buckhorn), with the 1A elevator 

An unmodified 21A is 0.358" tall. The "leaf" of the 22A is about 0.275" tall. And the 1A elevator wasn't provided just for looks.   

The Winchester 21 and 79 series front sights supplied by WRA for the 1885 SingleShot rifles normally had a german silver insert. The common 21 series was also less commonly produced as a one-piece all steel sight. 

The 79 Rocky Mountain front sight series has an almost 1" long blade. You could special order the 79 sight with a steel, copper, brass, or ivory blade, and it was available in two base widths, one for #1 thru #3 barrels, which had radiused sides, and one for #4 and #5 weight barrels which had the wider base to completely fill the front barrel dovetail, and which had squared sides like the 71A Beach front sight.

The 79 with a steel blade is pictured on page 185 of Campbell's first singleshot book. Note that the base junction with the blade is radiused, which is correct for a WRA sight. Winchester did not square the top of the base where it joins the blade. Ebay buyer's beware!

The 79 is similiar to the special order 73 series Knife Blade front sight, having the same bases, but with different blade profiles. 

Among the 22 series rear dovetail sights, the 22A Sporting Rear sight and the 22D Rocky Mountain Rear sight both were the same sight except that the 22D base was wider to completely fill the dovetail of the #4 and #5 weight barrels, the other measurements being the same. 

The 22 series rear dovetail sights with the cloverleaf, semi-buckhorn, California buckhorn, etc, were usually found on the earler rifles, with the flat-top becoming the factory supplied standard as the singleshot approached the smokeless era. 

Interesting thing about sights is that they are usually the first thing on a firearm to get messed with, altered, and changed out, and swapped by shooters and sellers behind the show tables. 

They have a history and evolution that is intriguing as a subcategory of firearms history, and you can accumulate a number of books and documents that are strictly sight related, if you have the inclination.
