3995 is still at Saltmeadows Road, so definitely not that one!
You're right in suggesting that it was 6138 - it wasn't re-trimmed as it wasn't scheduled for repaint at that time. It was at Saltmeadows Road for repairs to the windscreen, so treated to a partial repaint after the new windscreen had been fitted.
