Unknown Eat Static tracks - help with identification?

[jettson]

Hi All,
(I have also posted this to the Ozric Tentacles forum, before realizing there is an Eat Static forum also...)
I hope I'm not too off topic with this - I have four tracks that sound like they were produced by Eat Static, in or around 1991. However, I can't find them on any of their releases (I have listened to all of their pre-1994 'official' releases).
I thought someone here might be more familiar with rare/bootleg/sideproject stuff so there might be a chance to have them identified.

Links to 2 minute MP3 samples (sorry for the low quality):

In fact these tracks are featured on a 1991 mixtape from Sweden (the first 4 tunes on side A):

Any input would be greatly appreciated!
Thanks in advance,
