fill stations for scuba tank

might be a bit of a stupid question but how do i know what fill station to get for my scuba tank so it is the correct one

AFAIK There are 2 styles of valve - 'A' Clamp and DIN fitting

My own is an 'A' clamp rig, and I'll try to stick up a photo or 2 later. If you can stick up a picture of your tank valve I should be able to spot which type you have?
