Thanks, RUR, to the left of the Cremina is an Arrarex Caravel and to its right is a Faema Faemina. Both the Cremina and Caravel are full manual levers, the Faemina spring-loaded. The Arrarex does espresso only. As a previous Cremina owner, you know the disadvantage of this machine is temperature control, so you can't pull several shots in succession without the group getting too hot. But with a thermocouple / thermometer strip on the group and a heat sink like the OE Third Shot it's less of a problem. Which semi-auto are you using?
They're gorgeous and I may try to find the Faema. A quick Google search found a brief Faemina history and a parts supplier, but no machines for sale.
Actually, the temp surfing aspect of the Olympia (and recurring leaks, with problematic parts ordering from the factory in Switzerland) drove me to a Quickmill Alexia with aftermarket PID. I've had it about four years and it makes excellent espresso with no temp worries. Still, the old machines are works of art which definitely appeal to me. Once upon a time, I used to lust after a nickel/chromium plated Art Deco beauty in a small Heidelberg cafe whenever I'd visit, but the owner wouldn't part with it for love or money. :-(
The best place to find a Faemina is still eBay.it but, fair warning, condition is usually are much worse than used Creminas. And if the group requires some type of rebuild, the degree of difficulty with the Faemina is much higher. Not to mention Faeminas are almost impossible to find in 110V and the fact you'll still have to deal with the same temp surfing issues as the Cremina since the group is also attached to the boiler! In comparison, Orphan Espresso sells the entire Cremina part catalog nowadays so it's relatively easy to do a full rebuild.
Then again, coming from an excellent machine like the Alexia, if you'd like to get back to levers, then the "it" machine of the moment is the Bezzera Strega:
where its innovation is in combining a pump and a lever so you can run it like a regular HX all the way or use the pump during preinfusion (pulling the lever down) and let the spring do the pull (release). As for that "Art Deco beauty", if you still remember the brand and how it looked, then it definitely can be sourced.
