Here's two I've come across. If you search for them a lot of sites call it iron brew, highland bru etc. Personally I haven't tried them as of yet. Hope this helps.
Emporium Vapour.

Good juice, really nice and friendly people aswell, used to use them a lot when when I first started few year back.
Ive tried a few and this is the closest ive come across, i looooove iron brew this smells exactly like it but you want a Clapton or something to really bring out the twang otherwise it can be a little soft and fragrant.
