I know you posted ages ago, but if you're still interested in back issues of TF, try ebay and the Vintage Magazine Shop:
Tookaloo, apologies that nobody got back to you sooner. Are we too late to help out with your college project. Let me know if you still need issues 151, 155 and 157 and I'll see if there are any spare copies in the TF office. If you do, can you drop your address to one of the Mods (kiba or jonesy) and they can forward it to me. I'm the new Admin but my rank hasn't been set up yet so I won't ask you to send it to me directly - I could be anybody!
