Some of you may remember I posted a question or two about a Gibbs Farquharson rifle I picked up earlier this year that had been rebarreled to 45-70, I received a .461 #1 barrel from Glenn Fewless (he really helped me out there) and I have reshaped the forend to look more like some of the forends I've seen so the rifle is coming together back to an original caliber. My question now is on sights, I imagine finding an original is probably not likely and I've looked at some new express sights but just haven't settled on anything yet, anyone have a suggestion for me? anyone know of a vintage sight for sale that would be appropriate or where I might find something that would be somewhat period correct? Thank you
