Through the publication, around 1926, of a musical instrument catalogue describing the instruments manufactured in the Embergher atelier, it is known that Luigi Embergher classified his instruments of the Mandolin family in four groups: Student types-, Orchestra-, Soloist-, and Artistic models. For the mandolin this resulted in:
a. Two Students types, indicated as: the Mandolino da studio – Tipo A and Tipo B.
b. Four Orchestra models, indicated as: the Mandolino per orchestra – N. 1, N. 2, N. 3 and N. 4.
c. Three Soloist models, indicated as: the Mandolino per concertista e solista – N. 5, N. 5-bis and N. 6.
d. Two Artistic models, indicated as: the Mandolino Artistico – N. 7 and 8.
The characteristics of the models are described by Luigi Embergher in his catalogue, originally in Italian and French.

At the second page Embergher introduces himself through his renounced system of the plectrum played quartet, illustrated with a photo of the instruments of the quartet and himself.

Countless are the document writings and certificates by Italian authorities abroad: ministers, consulates, famous musicians and technicians. My concert mandolin is being asked for, used and praised by the best professors and mandolin soloists, even Italians abroad prefer my instruments to be used in the best mandolin circles, finding them to their complete satisfaction.
Third page of the catalogue:
Dear Sir,
I have the honour to present to you this new catalogue of my plectrum instrument factory. Without exaggerating their quality, I can say that after 45 years of experience and meticulous study, I have achieved a powerful, warm tone and a precision in sound which is unequalled, a fingerboard with an easy playability, a unique and elegant design; a complete perfection.
Besides the honourable decorations which I received at authoritative exhibitions I have been praised by press, teachers and musical societies in Italy and abroad, unanimously recognising the superiority of my instruments if compared with those of other factories.
With confidence that you will honour me with numerous commissions,
Yours sincerely,
Luigi Embergher
