what hull is this?!

[pigpen]

I'm trying to figure out if this is a envy hull or maybe a watercraft factory 1? Any input would be great. The guy doesn't know anything about the ski

Watercraft Factory---I seem to remember that ski.

It says WF in the turf.

That's what I was thinking, how do these compare to a stock sj? He doesn't know the specs on the motor or the pump which sucks but it seems like a good price for the ski?
