The tape set that came with my 'tron is marked "BBS" on each key, and is really worn, so it its quite possibly an original set.
If the 'BBS' marking is in bold felt tip squashed capitals then they are probably London produced tapes which were always out of azimuth! You can check this for certain as they have a drop out zone between tracks whereas Streetly tapes blended at a constant volume, as do ours now. The wrong azimuth gave them a nasal quality that some love.
