I'm posting these pictures for a friend of mine that he sent to me. He is not new to single shot rifles but neither of us know very much about Maynard rifles. We apologize for the less than good picture of the rear sight. It's a Freund, and we know it's mounted backwards.  

The rifle has matching serial numbers (including the hammer) with the exception of the side plate which has a lower serial number. He hasn't done a chamber cast but thinks it's a 40-60 Maynard.

He believes it's a Model 16 and is looking for conformation on that. He also wonders about the round barrel. The bore is in quite good condition and should be a fine shooter.

Along with confirming the model number and any other information on the rifle anyone can supply he would like to know a range of value for it as he plans to sell it. We both realize that appraising a firearm based on a few pictures and a less than detailed description is hard to do. However he would welcome any and all guesses as to a fair value. 

I can possibly get more pictures and we can do our best to answer any questions about this rifle.

That appears to be an Off-Hand No.16 1882 rifle. Full round barrels are not as common as part-octagonal barrels but it is correct.  Value will also depend on barrel length.

- Maynard Model No.16 rifles are typically chambered in .38-50, .40-60, or .40-70 caliber
- The rifle is missing its rack-and-pinion tang sight
    - It has a Freund Patent rear barrel sight (good) except that No.16s don't usually have rear barrel sights (bad).
- What is the front sight?

Yes, it seems to be an early 1882 #16. Round barrels were made by Mass Arms and since it is numbered to the frame I would consider it correct. No tang sight is puzzling as the #16 came with the rack and pinion sight. It should be drilled and tapped for the sight base and have the spring under the tang. It seems well worn and value depends on condition so I won't comment on the value.
