You pretty much got the story, that JC's came out in 44/45/46 so you have a rifle that was made /converted by a well known american company, right down to that rear sight idea which I've seen before. Its a rifle to shoot and have fun with, go hunting, beat it up use it up wear it out and keep the other original rifle at home on the wall safe from harm. $300 would get you an original one, go cruise on gunbroker.com for a good look at JC prices and conditions. if you haven't committed to the $300, either drop it by half, or you could pass on the rifle. If you like it for its character, try $125 and go shoot and enjoy it. Its not a bad deal and not a bad rifle, just in a different group than other enfields. There are other similar rifles by navy arms, go to enfield resource.com and look them up, their stuff looks similar and I liked the one or two I owned, even though the teak stain washed off in the rain, now that was a mess!
