Keith,
The beauty of Hellas is that many of the models are a lot thinner than most spots ( in marked contrast to Cibies which are often tubby little so and so's)
That( and the quality) is the reason a lot of people go for them ( I think Graham put up a post dealing with this when he was talking about his MGB)
The parent company- Hella KGaA is in Lippstadt, Germany but if you did want to chase up availability, then their UK headquarters is based at Banbury, Oxfordshire
I got some spare parts for one of their lamps a few years ago and I do have a telephone number: 01295 272 233. They may be able to point you in the direction of a stockist?
regards,
G
