Ok I spoke to my Dad he has had a look.
He could only see some from about 98-2001, but I reckon he just read off the spine, as you need to pick the mag up for the older ones to see the date as they were stapled. Fairly positive I have olders ones. He had a quick estimate at about 60-70 of them.
He also said I have issue 1, 2 & 3 of Mountain Bike World.
He doesn't want to post them though, so I am not going to be able to get my hands on them till Xmas. I am oop North, he is down in the South West. If I had known there was a market for them I would have brought them back up with me a couple of weeks ago when I was down visiting.
I will post up after Christmas with all the issue numbers, condition, features, etc. Sorry if that is bit too long for some but that is the best I can do.
