IMO you should be more in the ball park of 175-200
The sears rifle could be a Jukar , Maruku , or Markwell . If it’s a Markwell its worth near zip . If its one of the others 75-125 each . But then the prices for those old CVA , Jukar and Maruku’s are going up its not uncommon to see then in reasonable condition for around 200.. Personaly though I wont pay over 100.00 for one .
An FIE long rifle could have either a full 1 piece or a 2 piece full stock with a large brass casting for a joiner . Almost like a nose cap on a half stock .
Most were stocked in a red brass that was almost to the point of being bronze . I have seen a couple with iron and pewter though . They also used a couple different patch box designs
One of the big issues IMO for the FIE was the lock . . Not sure what they were thinking with that .
In fairness though , the lock parts do seem to be better in quality then the Spanish locks . that’s excluding the main spring which was way to weak even when you got a good one . However on the plus side , it should have a snail breech.
The rifling can range from good to bad . The largest % I have seen had rather deep rifling that wasn’t cleaned up . As such they often ate patches . So there could be a lot of work to clean up the rifling .
On the Sears rifle , as long as whats stuck down there is a brush , that wouldn’t be an issue . However if it’s a cleaning jag and patch that’s been there for years , then the barrel is toast even if it got stuck at the end of finishing up the cleaning . More times then not , what you will find is that the area where the patch and jag has set , will have serious corrosion , even though the rest of the bore my be fine .
If it’s a brush , it can be simply pulled with a brush tube . You can make that with a 3-4 inch piece of brass thin wall tubing that’s of bore size . Fit it to a wood dowel and pin it . Simply slide this down the bore . When you hit the brush , push past it . The brush will trap on the inside of the tube and then extracted .. Again this must be thin walled and of larger ID then threading of the brush .
Over all if you could talk the fella down to 175-200 for the complete offering , you could most likely get that and a little more by selling the rifles in parts if you decide not to do anything with them
