I recently acquired a Bb-A Trumpet engraved ‘Lavana - - Regd Foreign Manufacture’. Does anyone out there recognise this nam?. I have discovered Saxophones on the net with the 'Lavana' name and ‘Paris – Brevete’ but very little else and certainly no other trumpets. I think that items engraved ‘foreign manufacture’ are pre 1912 after that they had to have country of origin but not certain. Any info will be welcomed thank you.
