Brand is Courson. Made in France. Was not able to date as was made before 1969 and in 1969 there office with all the records burned down so no dating available on the older instruments.
Todays bands use a B flat tuba. But it would be good for someone to have at home to practice on, still sounds like a tuba, just could not play it in the band, but great for practicing on. Then would not have to carry the tuba home and back.
Just had a bunch of dents removed, the slides and valves all gone through so good and playable.
And if you are trying to get back into it, priced to sell.
