the only SS Ruger boat paddle in .264 that I've handled was a "1 of 1,000".
as far as price, it doesn't matter what we think they are worth. it matters what they actually sell for. I haven't seen a 77/.22 mag for less'n $800 in years. and, yes, i'll probably have one someday.
and the .264 in the link above has a bid.
and another on GB with box, up to $880
