Posting this additional Lux No.1 mainly because this one is marked '1A' as opposed to just plain '1'. But I've got no idea why. In every other respect I can see it is just the same as all the other 'No.1's! It can now be fired up again as can be seen. But having achieved this it will only be very occasionally in future due to leakage around the font base. Even getting this far took some doing as it had suffered the indignity of having been a polished ornament for some years, leaving a legacy of unexpected hidden problems.
