Does Anyone know this model of Cavagnolo?

[mok]

Hi!
I have an old Cavagnolo accordion. I bought it from the french seller on ebay and repaired in Seoul.
I love it.
But I don' know exact model name or production year of this instrument.
There is no number outside. The only number I found on bass reed part, it doesn't seem as a serial number.
I just guess it would be the 'Virtuose'.
I asked to Cavagnolo company, but they also couldn't identify the old accordion like this.
They only guessed it would be 'Virtuose 24'.

It has old and unique type of registers behind the keyboards.

If there is any specialist on Cavagnolo, I want your help. Thanks for reading!

Hi. I too acquired an old Cavagnolo recently, probably of the same era. Mine is a 3-voice LMM 4-row 100-bass with two sliders (4 registers). It has lots of decoration with small stones on the body. I asked Cavagnolo but they could not clearly identify the model. They made so many accordions, it looks like they did not keep records of all the models, also many of them were custom-made. Enjoy it! These are superb instruments.
