That is a fine looking sight Stephen.
What are you using for a rear sight?
I'm going to have to make one of those for my Hartford when I get my lathe doing again. if I ever will.

I use the Lawrence on my .44 hunting rifle but the front blade had to be filed down to just about the top of the rabbit ears to get a 130 yard setting with the ladder down and it is just to fine for me to see when the sun gets low.
I'm going to make the base so it's just above the flats that will give me a little more height for the blade so I can pick it up better.
This will go on my Hartford .44-77 with a Lawrence back sight and it will not be fitted with a tang.
I'm hoping this rifle will be done when I get to Big Timber in a couple days.
Leaving in the morning.
