Everything is made like fine watch parts.

Note: there are thick strips of platinum soldered to the sight staff and front sight, then the graduations are hand engraved in the platinum. The British did that a lot on high grade rifles.

Platinum did not cost thousands per ounce like it does today. 

It will not tarnish and has a grey silver color perfect for graduations.

I am a jeweler so Yes, I know it is platinum. There is a lot of platinum there!

This sight seems to be complete. It was probably made for a muzzleloading Long Range Rifle but it could be fitted to single shots with a new rear sight base.

There is only one flaw I can find. The small 3/8 dovetail front sight base works fine with the long cross feed screw on the front sight.

The threads slip in the front base that clamps on the barrel. A good machinist could probably fix that by installing a nut threaded to fit the screw. I know I could do it but no longer have a lathe or mill.

The little dovetailed box is very nice fancy Oak.

This is a great sight set with Lots of possibilities. I like just Looking at it!
