In other words, look at the model # of the item in the description. Use that model # and verify what the manufacturers website shows.
In the case of this Savage model #17400, I believe it is discontinued as it is nowhere to be found on their site. Googling "savage arms model #17400" produced a couple forums with people asking about iron sights. One of the replies was this: "Note: that particular Savage (mfg #17400) no longer comes with iron sights, so you need to confirm with the seller. Older productions runs do come with irons.". That information was dated 6.5 years ago.
Anyway, except for this rare case, I've always used the model #'s from Bud's verified with the manufacturers website info with 100% success.
