I had a similar situation with my 'Newcastle' van. The interior scrubbed up Ok after a wash with a sponge and soapy water, not exciting, basically the same colour everywhere cream cream and more plurry cream with a bit of very light green on a few draws down low. But that's the way it was back then so it looks original and that suits me.
Thanks for your well wishes, I am "well and truly 😆😃👍🙁☹️👎" ( depends which day we're talking about, it varies ) but I'm doing OK 👌
Keep the photos coming 😏 she'll be a top draw van.
Note the reference to 'the latest Scenic Wrap[around Windows. A special Roadhaven feature'. This suggests that Roadhaven was one of the first - or perhaps even the first - manufacturer to introduce wrap around front windows. Many other manufacturers did not introduce them until around 1960 or even later.
