Double barrel orginals?

[Will52100]

My father just got back from a flea market and told me about a deal he passed on.  Looked like an original double barrel muzzleloader, percussion shot gun.  Said it was pretty rough, but every thing worked.  They wanted 200$ for it.  Any idea what it would have been worth.  I figure just from his discription it'd have been worth around 400$ give or take, posibly less, posibly more.

Any ideas?

Thanks

depending on the maker could be as much  up around 5000 in new  shape .
 however i will say most likely less the  200 that was offered .. the auction sites have many originals  most all the time . few in possibly shoot able shape . one would have to look them over rather well to know for sure however .
 they go for anywhere from 50 to 75  to around 200 .
 I watched a very nice  what appeared to be  capable of being  restored  to shoot able shape for 275   Friday night . It was very clean . Stock in good shape  as well as nipples that appeared to have been replaced not long ago .

 i have i think about 15 or 20 originals in my collection  counting breech loaders . the most i purchased for 75 -200. i have a 1830's JW king,  14 gage  double pin , with 40 inch barrels  and carved dog head and serpent hammers that  i got for 1000  . but i knew the past owner , how he came to  own it as well as most of the  its story as far as a bureau trade gun , then back to England for refurbishing  in the 1850’s .
 There is a 100 years  lost section of knowledge   where it somehow made its way back to the states then west on the Oregon trail to here in Idaho   where it was found  in 1946 .
 She is in very good shape and I have had the pleasure of shooting it ..
 All that made it worth the received price . With out that I wouldn’t have paid more then 4 or 5 for it at the most

Thanks, after talking with my father the "roughness" he desribed sounds more like patina than actual rust pitting and such.  From his discription it was in pretty decent shape.  Wish that I'd have had a chance to get my hands on it, resale value notwithstanding, it'd be nice to own a piece of history like that.

If it was at a flea market & priced at 200, it was a $50. wall hanger. I guarantee that guy has had that gun to all the gun & antique dealers in the area & researched it in the gun books & on the internet.  Once in a while ya find something worthwile at a flea market, but it is rare any more, and even more rare would be a good gun.  (or a legal one !)
