Or you could look at them, and (most likely) photograph the relevant pages (or get copies made) for personal use, at the British Library. However, from what it says in their catalogue, that would entail getting a reader's pass and visiting their reading room in person, so if a trip to London would be more trouble and/or cost than it's worth for you, it wouldn't work.
Another possible source than e-Bay for second-hand copies is the Magazine Exchange (**LINK**). They currently don't seem to have anyone selling the issues you're looking for, but I have successfully bought old MB issues through them, so an alternative might be to keep a regular beady eye on what comes up for offer there.
