Hi Roy, congratulations on your purchase!
There is a description of what sounds like this particular model in the french book Renault Espace, la Voiture à Vivre by Serge Bellu and Dominique Fontenat. I think I bought mine on eBay years ago, but I'm pretty sure I saw it at the museum for sale when I was there in Romoratin three years ago. The description is on page 63:


I hope Lennart can be persuaded to shoot a series of photos of yours!
