Hard to say for sure really. I never see anything but brown, rusty examples of NY State guns, and they're almost all rifles.
Will the fact that this gun is so nice, and a carbine, justify the seller's price? Seems the ugly ones are going over $1,000, so maybe one that nice in a carbine will justify the over $3,000 tag. I wouldn't pay that, but then I'm not a Rolling Block collector. I love them, and if I did collect them, this would be a prime example, and it might be one that a serious collector has been waiting for.
