Old caravan photos/info 1950's

Kenf

Hello fellow members. Could I please ask if anyone could help me. I'm trying to help a friend who knows I'm a member of the Caravan Club. She is looking for photos, pictures, or information about old caravans she used to live in as a child. See section of
her message below for what she is looking for. If anyone can help I would be very grateful...

"Do you think that ‘caravan club of GB’ may have some old pic’s of vans from 1954-1960? Or, where can I look????? 

‘Whillerby Wanderer’, I think, and ‘Bluebird Homestead’. One of them, can’t remember which, was ‘brick-shaped’, but had ‘arc-shaped’ ends, that came down when ‘parked’ bedroom ‘ one end,  kitchen, [bath floor @ other end]".  

Many Thanks.
