Dellorto SHB 16/16 Carb

Hello Scooterists

I require a new carb for my 63 Vespa 50 special

It is a Dellorto SHB 16/16

The part on the SIP Web Shop is

Carburetor DELL’ORTO, SHB
Art.-Nr. 41020000

The problem I have is there is no picture. Can someone tell me if it is the model for the metal air filters or the model for the new plastic air filters?
