Interesting rifle, it is indeed a cadet action.  Nice pedigree on the builder, but unfortunately, it's not a particularly well proportioned or pleasing rifle overall; not what you would present as the pinnacle of his work.  The caliber is marginally too powerful (high pressure) for this type of action also, which limits the velocity and thus the usefulness.  Would still make a nice squirrel and rabbit rifle with lead bullets and reasonable loads. 

I'd venture a guess that if you get $1000 out of it, it's a particularly good day for the seller and the buyer was feeling generous.

My rationale for the value is:

Action, worth $300 to $350.  Scope worth $100 to $150.  Add $200 for the barrel work.  $250 for the stocks, only because of their pedigree, and you have to find a buyer willing to pay for that.  Otherwise, I'd value them at $50 to $75 as ebay fodder and consider that the rifle needs restocked.    

If you have any love for the rifle, it's highest and best use would be as a keeper, because you're in the best position to value it, as the current owner.

How does it shoot?  That can mean a lot.  Like women that are pleasant to live with and can cook or have a good job, a less than beautiful rifle is a lot more attractive if it operates well and is accurate.

These actions were made by Remington for the 1870 Navy pistol.  The cartridge was the 50 cal navy centerfire, bullet weight varied by ammunition lot, around 300 grains with a black powder charge under 30 grains.  The pistol actions were later modified to create cadet rifles using the same cartridge.  A very good condition Cadet is rare will typically bring the same price Dave is estimating this rifle.  Other like frame pistols were manufactured in calibers such as .22 rim fire, 32 rf, 32 S&W, and 32 WCF.  This is a nice delicate action and will make a lovely small bore sporting rifle as long as safe pressures are not exceeded. Even the cadet rifles seemed to be a bit awkwardly large for the action.
