Reduced hours of business until September:


On July 16th I begin weeks of outpatient hospital treatment which will fill my mornings. So at best only afternoon working will be possible, until about 5th September. We will try to send out orders as usual during this period. But there will inevitably be delays to our normal service. Website based orders will be much preferred over telephone orders if at all possible. And please keep queries down to essential specifics, not covered on this website. Thank you for special attention to paying the correct postage on non UK orders (chasing underpayments for postage occupies too much of my time as it is!).
