    Can you take a better pic :?

    From the angle you've taken it looks like IS for top mount and post on the bottom :shock:

    IS as covered in the FAQs.

    They look like IS. If it's an old Marzocchi fork they could be 48mm not 51mm IS
    Alpha, Beta, Gamma, Epsilon.

    Its almost certainly IS, but as RR has said, some Mazza's are very similar to but not quite IS, just measure the distance between the centres of the mounting holes on the forks.

    but as there is an Avid with what looks like a normal Post to IS adaptor in the picture?

    but all the info for measuring and the like is in the FAQs
