There is a Saddle Ring Carbine (SRC) with a barrel that is about 20". The full-length rifle is 24 or 26". I am confused when you say the carbine version does not look like yours, because there is not much difference in the two other than barrel length. The carbine does have an extra piece wood on the upper side of the forestock that is absent in the rifle model. Originals will have ladder sights, some reproductions do not. You can find them with both Winchester and Browning labels, but both are manufactured by Miroku in Japan. Retail new for both models is $1000-1100. Neither are in continuous production but apparently rotate through a production cycle every 3-4 years. In addition to .30-'06, the reproductions are offered in .30-40 Krag, .405 Wincheste, and (at least at one point) in .270 Winchester. They are fun and a novelty, but are not especially accurate (limitation on the design); are not particularly user-friendly for carrying all day (due to weight); and are not amenable to a modern scope (have to mount offset). They benefit tremendously from installation of a peep sight.
As a reference for you, the website for Collectors Firearms in Houston shows previous inventory along with asking prices. You will see them at $850 on up for reproductions and significantly higher for original antiques.
I am a potential buyer, if we can agree on what a fair price is and we can meet in Lufkin to conduct the transaction. We can discuss further in direct messaging if you are willing to revise your asking price.
