Special Offers

This page will be updated periodically giving details of any special offers. There are times when I have spare machine capacity, rather than leave the machine idle I use it to make a mirror. Such mirrors are advertised on this page. They are in no way inferior, unless otherwise stated, to my normal production mirrors.
