camshaft distinction mechanical vs hydro

[JIMP]

Hello all, maybe an easy question for someone, but couldnt find any relevant info, how can I distinguish a 4 rivet camshaft sitting on the shelf, if it comes from a wbx 1,9 or CT engine with hydro lifters or it is a post 71 1,6 aircooled with mechanical lifters, please give me the light!

There is a ring cast around the shaft part of the body,
 near the lobes and journals to identify a Hydraulic cam Dimitrios.

OK thanks a lot! I suspect what you may mean, as I dont have any in front of me now, I remember noticing a ring somewhere besides the center of the cam right?


Anyway a great help, thanks a lot!
