It is hard to put a value on it in the UK.
Remington used to put out a Model 700 Classic every year, in a different chambering, but they do few commemorativies. For 2006, Winchester put out the 1885 High Wall in .30-06. I handled a second-hand one for sale the other day, asking what it sold for new, $1,250.00. But a new 1885 in .30-06, when they make a run, is $1,679.00.
