I will start the ball rolling and then delete this later when you get a few more responses ( I like to try to keep posts down to make it easier for me to find things)
A Meteor that age that has never been stripped will probably need a new buffer washer, breech seal and maybe a mainspring.
I cannot comment of the scope, so will try to give you an idea just of the gun. One that age with complete open sights would struggle to get near £70 + postage now and probably £55 + postage would be closer and I think it would take a few days at that.
Knock off the sights and you have a £35 --£40 gun.
4 or 5 years ago a Meteor without sights for £40 -£45 (and maybe a bit more) would have sold in a couple of hours----now things are tight and the postage is killing the cheapies.
I cannot comment on the scope but I hope this helps and has not upset you.
