That's a reasonable point
@Big Squeezy Accordions - we live in a time where methods are changing. I accept it is common for manufactures now to mix leather and plastic valves. That said, I have owned a couple of modern instruments that had genuine leather valves throughout. I remember with Cooperfisa in particular you still have the choice of reeds pinned on leather (or cork) onto alder wood reed blocks. Or you can have reeds just waxed on red spruce - leather valves throughout. Actually, one of the nicest experiences I had just a few years ago was visiting Siwa & Figli factory to see their Super Quattro Artist line in celluloid and 50 year aged walnut. Again, leather valves were the order of the day. I loved the way they used decorative reed blocks in the stecca a billiardo finish. Let me show you...
This is the detail that makes me love the accordion. Look at the reed block finishing, see the different wood species. How about the double riveted reeds? Even now, in 2022, we don't have to settle for the new standard, there are still companies willing to go the extra mile. This company have started actually assembling their own proprietary reeds, with new patented reed head design. I asked them what their inspiration was and they told me, it was to be like the way Dallape were in the 1950s!
Maybe I care about things that don't matter, but to me they do matter. There are still impressive accordion builders doing special things in Italy, I hope they always retain their vision for generations to come.
