"Life Without Buildings": Which bass was used?

[swordofdestiny]

Does anybody know which bass guitar Mick used to play this? If the track was recorded prior to recording "Tin Drum" was it possibly his old Travis Bean or had he already bought the first of his Wal basses? He had his first one stolen if I remember rightly. He says he switched to a Wal during the recording of "Tin Drum" as the Travis Bean neck would warp due to the heat.

I know it's a bit of a muso question, but if anybody knows... Thanks.
