...where does DZN fit in?
My store has one with HBR12**, most on here are D*****.is there any reason behind the prefix and numbering, and what does HBR stand for ?
Probably nothing in particular. It's just a three-letter prefix, most likely specific to the UK.
Maybe the HB**** only relates to the non-MOE versions, check ?
Nope... My HBP is an FDE MOE model
