You will need the help of a gunsmith.
Use a punch and tap it across the barrel. Its a dove tail joint.

The standard mod 70 had a Winchester bead front sight on a ramp base with a sight cover. The standard rear sight was a Winchester 22G open sight. The rifles chambered for .375 H&H Mag had the Lyman 6W folding rear sight. Model 70 National Match (chambered for .30-06 only) had a Lyman No. 77 front sight on a forged ramp sight base and a Lyman No. 48WH rear sight. All receivers were tapped and drilled for popular scope and iron sights. The Model 70 Super Grade had a Redfield full gold bead front sight on a ramp with sight cover and a Winchester 22G open rear sight. (with acknowledgement to The Gun Digest, seventh edition, 1953)

Most came with a tooth ramped iron sight.But there could be different styles depending on the age of your Winchester model 1894 rifle,such as a peep sight,a full buckhorn sight,etc.
Yes. I doubt if Winchester ever produced a firearm without the company name or at least the WRA emblem prominently displayed. Slight correction to my previous answer. Winchester manufactured shotguns and a few rifles for Sears Roebuck and these will not carry the company name or trademark. However, even if produced BY Winchester as an exact copy of a company model, they are NOT Winchesters. The name Winchester is often stamped just to the right of the rear sight. -j. On 1894 and 94 rifles made before WWII, the name WINCHESTER is stamped on the upper stock tang. On post-war guns, it is on the left side of the barrel, below the rear sight.
Barrel, Trigger, Trigger guard, hammer/striker, front sight, rear sight, chamber/cylinder, frame, grip.
drift out with punch from left to right, muzzle pointed away from you.
Sometimes it on the top of the barrel near the rear sight. Sometimes it's on the side of the barrel.
Unless a different sight was special-ordered, it would have come with the Series 26 rear sight, which was made in-house by Winchester. sales@countrygunsmith.net
The Winchester Model 68 bolt action single shot .22 was made from 1934-46. It did not have a rear sight mounted on the barrel, but had a receiver mounted Winchester No. 96A peep sight (books at $20-40). As options, Winchester offered the Lyman No. 55W or 57ES Receiver Sights ($25-75). The hunt for old gunsights can pretty interesting. Lyman is still in business, and may be of some help. Good luck. By the way, the rifle (with sights) books from $275 at 100% to $50 at 60% condition.
The rear sight must move in the direction you want the point of impact to move. The front sight can be moved in the opposite direction.
