I'd been using TornEgo Mega Cartos and Atties on my SDs and Super Six via 901 to 510 adapters, but the adapter I was using on the SDs was too long (atty length) and looked crap...
So I asked Garry Dibley at e-cig city if he would make me an adapter to my own measurements and he kindly did - for free - what a star!
Anyway, here is the adapter - next to a regular "short" adapter:
Garry said it was a pig to make by the way
And here is the result - a Matt Black SD Mk2 with a TornEgo Mega Cartomiser fitted - I think it looks really good:
(The adapter gives a flush fit on SD Mk1 and 2 with TornEgo Mega Cartos and Atties)
