The 1964 threaded rod shows absolutely no rust or corrosion. I have replaced the other two with brass ones.

That looks definitive to me. No need for me to post pix or measurements (thanks to Sebastien for that).

For anyone not quite familiar with the three generations of La Pavoni manual home levers, this means there's functional compatibility between the first two generations (early vintage 1961 - 1974, and second-generation aka "pre-Millennium" 1975 - 1999). The Millennium machines, third-generation, have 51mm portafilters that are incompatible with the first two generations.

I don't believe the Richard Penney 49mm bottomless portafilter will be compatible with my first-generation machine, because it did not quite fit the pre-Millennium machine I once had. If I find out differently I'll post here.

It really should not be difficult to machine a portafilter for these machines. The "ears" are chiral (handed). The La Pavoni ones are LEFT handed, whilst MCAL and many others are RIGHT handed. Were it not for the "ears", one could make a naked portafilter in a few minutes using just a band saw and lathe, and making a "dressed" one would not be all that much more difficult. Even with the "ears" the task would be all that difficult.

I just looked at my Richard Penney portafilter and the ears are not directional, so it just may be a matter of filing them to fit.

Of course it's not difficult unless you don't own a lathe or CNC machine, or don't have proper metal working machinery, like me!

I have started both types, in stainless and with the optional bottom plate with spouts. We are making the wax pattern molds now. It should be fairly straightforward, but you never know.

Great! Keep me posted. I'd definitely buy an XT Portafilter for the La Pavoni Europiccola in 49mm

Thanks Jamie for mentioning my ad (in Canada I've sold three Naked portafilters already ). Yes, I'm offering NPF for the premillenium Pavoni as well. The first ones were machined just for our film (http://youtu.be/DvgcPQES7VM), but after the release the pressure was growing and the feed back too tempting.....

The first series was just for testing the demand for it.

Folks are happy with them:

There won't be any mass production of them in the future neither but I will start a small web-shop for them till mid of November.
