Hi Ron, not sure why you have put adverts up for the same thing but ...
you wont find any blinds going spare though Ron. The nearest you're going to find to be similar are those fitted to the Y-type saloons. There are pictures/photos around but no drawings par say. I have the roller, toggle and blind ends but hadn't completed that resurrection bit before putting D0407 up for sale.
