Got the option of buying a Merlin at a good price, but has not been used for about a year, obviously the membrane/filters may be shot, but looking at Merlin pics on suppliers websites this Merlin has slight different colouring, so could this be an earlier one?
Anyone know how many versions/types of the Merlin there have been?
Would the membrane/filters on sale at suppliers fit any previous Merlin?
Questions questions

Cheers
