..... I have Lymans on one M94 and Williams on the other. The Lyman is a bit better design and quality I think, but also more than double the price !!! I have a Williams rear here now that will fit the 1895 to get me by, just need to source the front sight.
I am actually looking at a set from here....

Andy, definitely give Skinner a go! I have Skinners of several various types on all three of my Marlin lever guns and you can't go wrong. Hmmm, come to think of it, my 45-70 is a SBL, and I think that is original equipment with an XD ghost. I have not replaced it as it is perfect as is. Fast and confident target acquisition. Fine out to 100m/yds. I have his paired ghost/peep and front shrouded post set up on my 44 mag. Again, fast and sure. The shroud works without the historic problem involving the mistake of sighting with one of the shrouds when moving fast or in low light. The design is such that the shape of the shrouds just does not allow that with my eyes anyway. His peep works beautifully on my 22 also. (The .22 was my dad's first rifle which he bought in the mid-50's. That action in like buttah!) If you want pics and or model numbers re the sight used I can pull that off tomorrow.
Cheers!
