Hello, I am reader here for a long time. Recently I got a very nice Zacconi Riviera flat top spring lever machine which I think it was produced in 90s.
I have read some successful cases feedback at here on using a 45mm Zacconi Riviera double basket on a Pontevecchio Export bottomless portafilter. Maybe some tweak has to be done on the Zacconi basket was required. But I have a different case.
My Zacconi double basket, which came with the machine, doesn't have a dot. It has a flat top. And the barrel wall isn't that straight. I got the bottomless portafilter at here:

The Zacconi basket barrel seems not fitting my Pontevecchio portafilter.
This is my machine
This is measure of the inner basket

Should I buy a new basket for Pontevecchio Export? The PV Export Portafilter can mount to my Zacconi Riviera in a pretty loosen manner. I have to turn a bit more to mount it onto the group.
