GOSH, TOM!! Such violence on the ZONE.
I'll take "Lady of Spain" out of my repertoire; IMMEDIATELY. Sure would hate to get shot for my second best performance! I play TICO TICO much better.

Dicki, I'm not familiar with the material or the article to which you refer. I am not an aficionado of accordion history in the US, although, there were several compainis here. Excelsior and Imperial for sure.

The quest has always been for lighter weight. A first-rate acoustic accordion will weigh between 22 pounds for a stroller, and up to 30 pounds for 4/5 piano accordion.

Of course the reedless accordions are much lighter; SEM CIAO at 14lbs. and Roland at about 18lbs.
