What kind of concertina is this?

From the right side it looks like a Jedcertina, which mimics a piano keyboard (white notes and black notes laid out as expected), but the Jedcertina has the same pattern on both sides and this one doesn’t. I don’t know what to make of the pattern on the left. I’ve never seen one like this.

I wonder if the left hand side is a very small accordion type bass, as seen on some very small piano accordions.

It looks the same as one I have listed/illustrated in my 1939 Hess, Klingenthal catalogue, described as a ,,Cromatic"-Konzertina, and I've seen similar examples that have a piano-system right-hand side, with a German-concertina diatonic left-hand side, just like it.

 

It's late here now, but I'll scan, and post, the listing tomorrow.

I think that woodworm has some concertina in it...

I counted out the number of worm holes. It is even, so the worm is out. No reason to worry.

Here's the 1939 Hess, Klingenthal, catalogue listing that I spoke of. Compare the instrument in question with the lower right one...

I've been to both of them.

[sven6side]

I bought the instrument.
There are many more wormholes on the inside. And inside the blocks.
The wormholes are the least of my worries.

 

Everything is fine!

[sven6side]

So this is a  "cromatic-konzertina"  -   inside . . . . .  

[Peter Smith]

I have one of these - fortunately not ridden with woodworm. A large concertina measuring 20.5cm across the flats.

The right side has the piano layout, covering 1.5 octaves from E (above middle C) to G.

The left hand is an anglo type layout with single notes. Top row in F and bottom row in C.

All buttons play double reeds.

The layout is as follows:

Top row  Pull/Push  C/F  E/C  G/F  Bb/A  D/C

Bottom row              G/C  B/G  D/C  F/E   A/G

 

I will attach a picture.

Nice picture of a nice Concertina. Is there a picture of the inside, and especially the blocks? Is the block glued or screwed to the base plate?
 

[Peter Smith]

The reed blocks are screwed into the action board.

Standard German construction with wooden levers. 

See attached photos.

[Peter Smith]

Just noticed that the reed blocks the other end ('anglo' end) are glued to the action board.

[sven6side]

Thank you.   Mine is/was screwed AND glued, and the wood is softer than balsa.   And I have not even looked on the other side.

    And this is how it was when I opened it the first time. 

[Peter Smith]

Just come across a reference to this instrument.

It is called a Chromatine.

The combination of piano system on the right and concertina system on the left goes back to Georg Mirwald from Söllitz in Bavaria, first made in 1890.

I think that 'woodworm' in the sample [ auction] is natures own way of making a sort of additional decorative design, like the pierced woodwork already on the instrument!☺️ That maybe is why they call a tune a 'worm' if it goes roud in your mind on hearing it often!
