Hohner Diatonic?

[Mr Mark]

I'm working on this little box and am trying to identify model and year. Some insight on tuning would also be great as I don't see a lot of diatonics. It is a Hohner but no other markings. The 4 Basses are D/A, G/C, Bb/Bb and C/F. The stamps on the reed blocks seem to indicate this is then a C/F.

There are three reeds in the treble section, unfortunately it was in very old shape when I got it so discerning original tuning is almost impossible. However, my readings seem to indicate an M/M-/M- configuration. To what extent of tremolo though I am not sure.

Looking at the Hohner list there are only two models with 21 treble buttons in three reeds; the Corso and the Italiener. The Italiener is a very old model (29-31) so I am guessing this is a Corso. If that is the case what vintage might it be...the years produced vary a lot (56-63, 73, 87, 95).

Any help is much appreciated!

1930-1940

Somewhere in the quagmires of accordion related internet I found one of these that someone had drilled holes in the reedblock to 'help' the high notes (1 hole each in the top two notes through the top of the reedblock maybe 1/16" in diameter or less?). Alas I closed the page and can't find it again, I have not heard of this before or seen it anywhere so...what gives? Hopefully I can find the picture again.

I ended up going with a reasonably wet spread (+/-18 cents ~ +/-6 cents) and it sounds FREAKING AMAZING. I love listening to awesomely tuned accordions literally chopping the air physically into sounds.
