I'm assuming you mean the iron sights mounted to the barrel of the rifle? Elevation is adjusted by sliding the sight elevator front to back on the rear sight. Windage is adjusted by drifting the front sight left-to-right. If the gun is 'shooting to the left' tap the front sight slightly to the left. A very small movement will have a major change. You could also tap the rear sight slightly to the right to effect the same change. If the gun is 'shooting low', slide the sight elevator toward the rear to lift the rear sight leaf. Again, a very small change in adjustment will have a big impact downrange. sales@countrygunsmith.net

adjust rear sight up for distance
A Winchester 94AE has a modified ejector that throws the spent case to the right making it easier to mount and use with a telesopic sight. The AE means Angle Eject. These were produced after 1966 in order to compete with the side ejecting Marlin lever action rifles.
I would first look to numrich arms in as they specialize in old gun parts.
the ranger Mod 34 was made by Marlin mod 65 e-GunParts.com
Depends on the firearm.
At the website for gunpartscorp.
Between 350-550 dollars,depending on overall condition and a good bore.
I just got one for $70, it is missing the front sight. Other than that it looks good.

Very little info to work with! It could be a model 39, but no way to be sure with so little information. If there is a tang sight mounted behind the hammer, remove the two screws, and the model designation should be on the top tang, under the sight for a model 39. If it's not there, then there's a lot more info on the barrel than just the Oct 38 info you gave. marlinguy@juno.com
Via the screw.
