Schiedmayer from 189x

Hi all

As mentioned couple days ago under another topic I post couple of pictures of my Schiedmayer harmonium action. I was wondering it's strange mechanism that differs from usual 2 set of reeds harmonium.
When I bought this instrument I was not able to test it due to cracked pallet timber and didn't have a clue how it might play or sound.

There are 8'+16' ( (1) Cor Anglais + (P) Pedal Bass ) reeds in bass and 8'+8' in treble ( (1) Flute and (C) Cremona ) then Melodia Cremona stop.

Now when I assembled action back together and looked it more carefully I realized functionality of action as a whole.

If you look 3rd picture you'll see additional mechanism on the top of the keyboard. When Pedal Bass stop is activated mechanism allows only lowest note pressed play from 16' reed set and all notes from Cor Anglais 8'. Similar functionality is when Melodia Cremona is activated. Then only highest note at treble side is played 8'+8' and rest of treble plays only Flute 8'.

Have someone from this forum seen this kind of action used by some other manufacturer or is this only Schiedmayer specific?
I find this quite unique way and I'm more interested to feel and hear how this instrument plays after bellows have been repaired.

I'll keep on posting pictures when something is available.

I didn't translate this with google, if some one is willing to translate this to French please do so.

Cela ressemble fort à une extension aux basses aussi du brevet Dawes, que Mustel avait commencé à exploiter sur certains instruments. Là, il s'agissait sur les jeux arrière (3, 4, 5, 7...) de n'avoir que la note la plus aigüe qui joue.
Avec ici un effet miroir, vous avec aussi la même chose pour les basses.

This looks like an extension to basses of the Dawes Patent, that has been tested my Mustel on some of his instruments.

C'est une variante de Basskoppel et Melodiekoppel qui sur des orgues romantiques allemands n'accouplent que la note inférieure ou supérieure d'un accord. La fonction est de faire ressortir la basse ou la soprano un peu plus que les autres voix.

Des détails (en anglais, désolé, pas le temps de traduire !) sur le "melodic attachment" de Dawes ici :

Thank you Mathieu and Louis for the information. Seems that I have more interesting instrument in hands than I thought at the beginning.
Now I really must speed up other projects so I focus on this one.
I'll post pictures of this project when it is back in one piece.
