The last time I spoke to Jackie she told me this kit had been withdrawn. As with printed circuit boards, die-cut styrene sheets and GRP hulls are expensive and you have to buy a lot of them to make the exercise cost-effective. If sales of the item in question are limited to a few a year then it's better sense to invest in more up-to-date and saleable lines.
If you ring then you may find they have enough parts to make up a kit for you. 01226 770008 usually gets through.
