Scintilla S.A. Soleure Switzerland RARE sewing machine (portable)

Old sewing machine (portable) Scintilla S.A. Soleure Switzerland RARE !!!!!!
This rare travel sewing machine that rests on a wooden base where you can take it off and place it in the matching case.
After much research, I discovered that this sewing machine was made in the factory of Scintilla S.A. Soleure Switzerland and after further investigation it appears that Scintilla AG was founded in Zuchwil in 1917 to be a subsidiary of Bosch, including Bernina
The original tag plate contains these data MGG729LZ2 - 8045 or lock 045 and inside the sewing machine in the iron part this number is stamped S 84470
I have tried to find all possible info and after the long search I have NOT found ANY model of this type.
This machine was from a professional tailor.
Condition of the device working and in a beautiful condition and matching pieces, even the original needles are present, only the original case has suffered a bit.
