My baritone set up is...
Selmer mk6 low A
Meyer HR medium #7
Meyer lig
Rico Royal #3
The horn serial # is 190,xxx. I bought it new from Charles Ponte in NYC back in 1971. Paid $850.00, a king's ransome back in those days. Probably worth at least $1000.00 today.:-D The horn sold without a mouthpiece, but Ponte threw in a nos Woodwind NY big old hr #4. It was a beautiful piece, never played, but very old. I had been admiring it while closing the deal on the horn. I pointed out a small lacquer defect on the sink drain part of the horn, so he threw in the mouthpiece. I don't think that it would happen that way today.
Another thought is coming into the side of my brain......I scoured music stores for just over a year before I was able to find this horn. I was looking for a new Selmer Paris baritone, preferably a low A, but the low Bb would have filled the bill. No one had either. I searched stores in Philly and NYC, phoned, and walked in, left my phone #. Thinking back to those days, I realise that there really weren't that many baritones of any make to be bought brand new in that year. Not in my area. And I don't believe that it was because of a lack of bari players, I think that it was because of the fact that by 1971, Selmer had just about ruined the competition courtesy of the mk6. I don't remember seeing new Conn, King, Martin, or Buescher bari's during my search. By 1971 these companies weren't much of a factor as far as professional level saxophones were concerned. H. Couf was around, and some players were going there, but the big 4 seemed to be winding down. So Selmer was busy keeping up with alto and tenor demand, and could afford to build baritones when they got around to it.
