Not sure what a "cody" scout is, never heard of one.
I had a 50 cal scout, which was an inline that used #11 caps on a large nipple/breech plug. Kind of looked like an old Winchester without a lever.
These were also made in 54 cal. Both calibers were not great shooters and a pain to clean. TC screwed up with the barrel twist in these guns big time, 1:20
although I have heard some were 1:28, not sure on that one.
IMO it is probably not worth more than $150 and then only to a collecter.
My guess is the scope is a Lobo on a rail mount.
A picture would help to give you a positive identification.
