Io non lo avrei preso, neanche se costava poco ...... Se prendevi un Committee II (the Martin Tenor) avevi un gran tenore questo invece ..... :BHO:
Martin Imperial saxophones
Made 1950 - 1970 (Ser# 300K - 320k - a lot missing here) Classification: Intermediate

The Imperial model is a intermediate line horn.

As it is sold in the same era as the "The Martin" and later on the "Magna" in which period also their student horn Indiana was made I think one could safely say this.

Someone described it to me as:
Not a bad horn, good intonation and tuning, but with a thinner empty tone (compared to a The Martin)
