Missing Enigmas

Any help in sourcing the text for the following puzzles would be much appreciated.

The following are puzzles I have been able to transcribe correctly (I think), even though I do not have an original source image, so will be able to post them, but I would appreciate a complete source image in order to verify my transcription:

• Enigma 938: Trios of primes / 2nd August 1997
• Enigma 931: Primes and primes / 14th June 1997
• Enigma 923: Chain of squares / 19th April 1997
• Enigma 828: A line of boxes / 24th June 1995
• Enigma 11: Kid’s stuff / 3rd May 1979

And I would appreciate a legible source image for any Enigma puzzle that does not have a linked image (or has a poor quality one) for reference purposes.

The following Tantalizer puzzles are missing from the Google Books archive, so I do not have a transcription for them:

• Tantalizer 300: Gogol / 21st June 1973
• Tantalizer 217: Simple arithmetic / 2nd September 1971
• Tantalizer 180: Voting behaviour / 24th December 1970
• …
• Tantalizer 51 / 1968

Puzzles from 1970 – 1989 have been transcribed from the Google Books archive of New Scientist magazines.

Much of 1990 – 1999 are transcribed from images sent to me by Hugh Casement or others, or from the New Scientist web site (although this can lead to missing diagrams).

Puzzles from 2000 – 2013 were transcribed from physical copies of the magazine (although I didn’t keep the images for all of them).
