basic history
Chromatic button accordions imported into the U.S. are subject to customs duties. Piano accordions are not. Make of this what you will.
Thank you for the Giulietti patents links and the basic history of the accordion.
A lot of interesting data and info on this basic history website.
The 1877 year mention of the birth of the Vienna Schrammelharmonika (the first B-system chromatic button accordion known) is very close to Andreas Teufels findings. He wrote a thesis on the Schrammelharmonika (pdf for download). In this document he talks about the year 1874, but there are no (online) documents to verify this.
I would love to find and see the 1890 patent by Rosario Spadana from Catania, Sicily:
1
[font=arial, sans-serif]890: [/font][font=arial, sans-serif]Rosario Spadana[/font][font=arial, sans-serif], from Catania in Sicily registered a copyright for a free-bass[/font]
The first real free bass accordion in history with documentation is the F. Gerl Hand-Harmonium from 1891:

There is even a tutor/method for this Gerl Hand-Harmonium that has survived, but it is in the hands of a French private collector, sadly no online copy on the net.
A few accordion bass convertor online patents:

quote:
[font=Arial, Helvetica, sans-serif]In 1907, P. Sterligov created this instrument which was so different from all other existing harmonikas (so-called garmoshkas). He gave this instrument the name bayan according to the old Russian singer Boyan. The specifications were: 55 treble buttons (4 rows), 72 basses (with preset chords, often known as standard bass).[/font]
[font=Arial, Helvetica, sans-serif]In 1929 Sterligov built the first bayan with single tones (bass) with a new bass meachanism that permits, by pressing a button, to switch from standard bass preset chords to single notes of many octaves. This invention considerably increased the performance of the bayan.[/font]
[font=Arial, Helvetica, sans-serif]I am looking for an online patent or picture of the 1929 Sterligov bayan convertor.[/font]
[font=Arial, Helvetica, sans-serif]Joseph Galleazzi (Giuseppe Galleazzi) patent 1894 with preset chords, years before the 1907 Sterligov preset chords bayan.[/font]

One of the first free bass accordions in history actually was a concertina, the double duet concertina by Charles Wheatstone (a 4 columns chromatic layout free bass instrument), described in his 1844 patent:

A different instrument but the idea is basically the same as a 3 rows free bass accordion.
Thank you for bringing this to our attention:
Chromatic button accordions imported into the U.S. are subject to customs duties. Piano accordions are not. Make of this what you will.
Are you based in the USA? Do you have any ideas or explanations for to this different treatment of PAs and CBAs by the customs duties?
