Can anyone identify this Vespa front hub?

Im trying to identify this Vespa front hub (If the photo is uploaded!) The part number on the back is 991835. I'm presuming it is a PX or poss PK hub but can anyone confirm what it is either way?

Looks like a PK to me

Thanks both for the answer. As a second point, do PK's use the same hub. So would this fit a 50 and a 125?

Only the XL2 varients, the first series PK and XL 50's used a V range type fork and small drum front hub.

PK 80-100-125 ...which has got the px style fork set up it will fit
