"Chris played Teachest Bass "

I'm fairly sure that this is wrong. When Chris Barber had his skiffle group in the days of the Ken Colyer band and in the early days of his own band, there was sometimes a "skiffle spot" led by Lonnie Donegan in their jazz club and concert appearances. In these skiffle spots Chris would play bass but it would be a regular musical double bass and Chris was always a skilled player of the instrument. He usually switched to double bass when Monty Sunshine played his solo in Chris Barber concerts and I think he was also on double bass when Monty made his hit recording of Petit Fleur.

Tea-chest basses were common amongst the rank and file amateur skiffle groups, but Chris Barber was much more musically sophisticated than that.
