Dovetail measurement

[Hanz]

I'd like to order a replacement front sight for my Shiloh Sharps 1874 from Distant Thunder and I don't want to screw this up.

I drifted out the front sight (left to right) and have measured the base of the sight at .4365" and 7/16 is .4375".







What has me confused (it's easy to do ) is they list a .450" that they have labeled as Shiloh.

"It is currently available in 3/8" dovetail as well as .450" (Shiloh) and 7/16" (C. Sharps) dovetails."

I know you can't argue with the measurement of what I have. Anyone else have a Shiloh with a 7/16 front sight dovetail?
