That’s what Iran’s IAEA rep Ali Asgar Soltanieh says, “according to Fars News”:http://english.farsnews.com/newstext.php?nn=8801291027:

bq. About Iran’s new centrifuges, Soltanieh said, “Previous centrifuges are not centrifuges of Pakistan class – they are “Persian” class (P-1, P-2 or IR-1, IR-2).

Yep. And in Libya, the P-1 was called the L-1.

Now, as Iranian nuclear-program howlers go, that doesn’t crack the top ten. But let’s recall all that LEU and HEU cross-contamination found on Iran’s first set of P-1s, some of Khan Research Labs’ castoffs. Would Mr. Soltanieh care to take credit for those traces, after all?

Once upon a time, of course, some devices not unlike the P-1 were called “SNOR and CNOR”:http://www.armscontrolwonk.com/1401/when-did-pakistan-stop-stealing-urenco-designs. But now I’m rehashing ancient history.
