Haven't too many now, Katrina took all the old ones. But in the last year have picked up a few to play with.
Open on one Chinese side lever...not the original sight, but one from a firend's junk box. Not my favorite gun, and older one that's a bit "harsh", but it shoots well and stands ready at my back door (new house).
Open sights on an old (about 1970) Sheridan. That one came with the old scope mount (the one old long mount) and an old 4X no-name scope on top...but it also came with a partly detached barrel. Considering how Benjamin and Sheridan's mounting system works, doesn't take much of a knock to a scope to ruin the barrel joint. That one got fixed and resealed. Intended to put an apature sight on, but after testing the iron decided against it.
Apature on two. One is a recent 953 with a home-grown trigger job (as outlined at pilkgun). It's wearing a match sight from a gamo 128 rather than the Daisy sight. The other is a QB79. Both work fine for me out to 40-45yards (all the range I have to shoot).
That old gamo 128 (that's Gamo's old entry into the full-match gun market...a single stroke pneumatic wih a trigger every bit as good as my old FWB 300's) donated it's match sight to the Daisy and wears a 6-18 Simmons Airgun scope. Kind of odd for a 600fps air rifle, but it's consistant enough to use it.
Wandering though a local sporting goods store, noticed a gamo 850 with 4X new in the unopened box on sale for $74. Cheap 4X scope died...cheap munts died. Better mount and an even cheaper 3-9X scope. 3-9X Simmons that a freind gave me with a broken reticle. Readjusted the paralaqx and carefully made a post. Post is thin enough to work well, and attched strongly, so I doubt recoil will break it.
So far that's it for long guns...did pick up a good Dasiy 777 (love those steel sights), Gamo Compact, Crosman 150, and a Crosman MkI. Treated myself to an "izzy" as well, but my wife kind of confiscated that one for her own use.

For those who missed it, here's how you can replicate Katrian's effects on guns:
1. Get a take 11.5 feet deep and about 10 feet wide (at least at my old house that's how deep it was).
2. Fill it with filthy SALT WATER.
3. Add a dozen shovels of dirt.
4. Add in some of every chemical in the house...bleach, drano, amonia, gasoline, etc. a bit of everything in the house.
5. Toss in a dead cat and take a dump in the barrel.
6. Toss in ALL YOUR GUNS.
7. Roll the barrel around for a few hours (water was moving fast enugh to toss a truck through the back of the house)
8. Punch a small hole in the barrel (want it to take about 22 days to drain).
9. Walk away for 28days of +90degree temps.
