I have a 74 Devon Eurovette i can send some photos of but Devon did several differnet conversions a that time. You could try a google search to identify your model. Try Caravette, Moonraker, Sunlander & Devonette as well as Eurovette. You could also try www.devonmoonraker.co.uk where i managed to download a copy of the original 1974 Devon owners manual
I've got a '76 Eurovette. The roof will be different to yours but the interior should be the same (the fridge was an optional extra so you may have a cool box under the sink): If there is anything in particular you want a piccie of let me know and I'll pop out with the camera.
thats it im look for a cupboard handle/latch like in this pic http://i1083.photobucket.com/albums/j388/lobielove/gallery1218529107.jpg
